My application no longer connects to ClouDB

hi since i have ai2 offline, i work alternately on online and offline.
But I noticed that my application which uses cloudDB does not connect to it at all after compilation.
I would like to know if there is a reason for this and if I can fix it

Which version ? ai2offline or the official site : https://ai2.appinventor.mit.edu ?

I use the two versions alternately, I import the project from one to the other and vice versa.
and it's since i did that that it stopped connecting to cloudDB. Otherwise at the beginning when I was only using the online version it connected very well

Why?......

i am not always connected to the internet. I even often disconnect so it allows me to move forward on my projects

I think you should make a choice. The offline version could be different from the online version and that could give errors. What offline version are you using?

I don't know how to identify the version.
But I understood I should no longer use the same project on the 2 versions.
Thank you
