Open Messed up Join Files on Drive

Hi there,

I recently purchased a new Mac and tried to install Join on it. I'm using my google account to sync my chrome settings across my computers. I had to reinstall JoinChrome manually since I'm using the Github version and using the beta app on my Android device.
I was asked to give Chrome a new device name since it was already used by my previous computer. Join is working fine but I could not get the SMS on the chrome app on my new laptop.
I tried cleaning up my Join Files folder on Drive, uninstalling Join from android, nothing worked.

Now Join is creating more Join Files folders than it should on my Drive account. It seems that every time I go trough the process of reinstalling everything it creates a new copy.
As I've been working myself with the Drive API recently, I think the issue might be linked to Folder/files ID problems. Is there anyway to get rid of every saved ID for my account ?
I looks like right now my devices are not using the same ID for the Join Folder, one is looking for a folder ID 1 while the other might be looking in a folder with ID 2.

I currently have 4 Join Folders created on the root of my Drive when I tried my last cleanup

 

Hi, thanks for your reply. I already tried that multiple times, but it does not work
