Hi @jcpmorvan. I'm going to ask you to provide the full output from a compilation.
This procedure is not intended to solve the problem. The purpose is to gather more information.
Please do this:
Open your sketch in Arduino Cloud Editor.
Click the ✓ button in the Cloud Editor toolbar.
Wait for the compilation to fail.
If the black "Console" panel at the bottom of the Cloud Editor page is minimized, click the ˄ icon at the right side of the "Console" toolbar to expand it.
Click the icon in the top right corner of the black "Console" panel at the bottom of the Cloud Editor page that looks like two pieces of paper ("Copy Console Output"):
Open a forum reply here by clicking the "Reply" button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the compilation output is correctly formatted.
Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the compilation output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the "Reply" button to post the output.
In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here.
Select the .txt file you saved from the "Open" dialog.
Click the "Open" button.
The dialog will close.
Click the "Reply" button to publish the post.
Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.
Thank you for the fast reply with clear instructions

Arduino Cloud IoT Thing sketches must have access to the Internet in order to communicate with the Arduino Cloud server. For this reason, you must configure the Thing with credentials to access your Wi-Fi access point. The sketch is failing to compile because you have not configured those credentials.
I'll provide instructions you can follow to configure the network credentials:
Click the following link to open the list of your Arduino Cloud Things in the web browser: https://app.arduino.cc/things
Click the name of the Thing.
The "Setup" page for the Thing will open.
Click the button ("Configure") under the "Network" section of the page.
The "Configure network" dialog will open.
Type the SSID of your Wi-Fi access point into the "Wi-Fi Name" field of the dialog.
Type the password for the Wi-Fi access point into the "Password" field of the dialog.
Click the "SAVE" button at the bottom of the dialog.
The dialog will close.
Select the "Sketch" tab at the top of the page.
The Thing sketch will open in Arduino Cloud Editor.
Now try compiling the sketch again. This time it should compile without those errors.
You will continue to see this message even after fixing the network credentials, but don't worry. When you compile a sketch, the Arduino sketch build system searches through all the installed libraries to find the ones that contain each of the header files specified by the #include directives in the sketch code. Multiple libraries might contain a header file with the specified filename. In this case, the sketch build system must decide which of the libraries to use.
The "Multiple libraries were found for ..." message is only communicating that this happened, and which of the libraries was used. The sketch build system is pretty smart in how it chooses the library so usually this message is nothing to worry about. Just take a quick look at the message and if the expected library was used then you can safely ignore the message.
The only time you need to pay attention to this message is when Arduino IDE picked a different library than the one you had intended. In this case, it will be necessary to take some action to cause the correct library to be selected. If you have that problem, just let us know and we'll provide assistance.
For the convenience of the user, every one of the thousands of libraries in the Arduino Library Manager are preinstalled on the Arduino Cloud server. This means it is likely that, for any #include directive for a file that is named using a common term, multiple libraries will contain a matching header file. So it is expected that you will often see these "Multiple libraries were found for ..." messages when compiling your projects with Cloud Editor.
After correcting the thing for the network, the sketch verification and downloading went well. I should be able to start my project that is a both ways communication to display info and control activities on my sailboat from my iPhone.
Thank you very much for your precious help. Your instructions are clear, complete and to the point.
A great assistance job.
