Hi guys ,

Who can resolve my problem ? :confused:

There's a very similar problem posted in the French section

4

Many people have had issues using ONEDRIVE.
The answer in most cases is to move the sketches location back to your main computer.

5

Shouldn't this be in the Programming section ?

...R

50/50 at the moment R2.

If it is a one drive issue then its probably better here.
