"That's pretty weird. I do have projects with many variables working perfectly fine. Can you share the sketch that is not working so that I can try to reproduce the effect?"
Yes, please try to help me make this work. Is there a way I can do the Thing variable updating myself in code rather than having it be done in the background? Maybe with the ArduinoIoTCloud library? I need to be able to send SMS messages from within my cloud application, so I need to pause the Thing variable updates, send the SMS, and resume.
Here are my Thing variables. If I add one more Thing variable, the cloud stuff locks up, my main Loop executes three times before the lockup. Then it is almost impossible to reprogram the MKR NB 1500 again because the watchdog goes off in the middle of the upload process. I have a total of 21 Thing variables I want to use.
Here is the code. I am running a new clean build of Win10 because i wanted to be sure it wasn't some windows thing. I had the exact same results using a different computer. Note, I had all of the Thing variables linked to widgets on dashboards too.
Depending on how interested you are in getting to the bottom of this problem, and want to work with me at the same time,let me know your time zone and what time you would be available, and I will be here to work live with you. This is very important to me as I have the potential to lose lots of money if I can't get this to work. Thanks in advance!
Oh, I commented out the callback code and had the same problem either way.

Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
String status;
String testValue;
int area1;
int area2;
int area3;
int boardO3analog;
int number1;
int number2;
int number3;
int potentiometer;
int seconds;
bool led;
Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
which are called when their values are changed from the Dashboard.
These functions are generated with the Thing and added at the end of this sketch.
