Cryptomator ios

I downloaded cryptomator on my mac and seems to be working fine with google drive and icloud .
Now i purchased the IOS cryptomator app on my iphone and it seems that it works independently, meaning that it can’t see and open the files i encrypted and saved on google drive through my desktop app. And secondly, the mobile app it is not recognizing the cloud drive on my iPhone !!
I just feel that this cryptomator is very user-unfriendly !!!
Any advise would be appreciated

Please check that your vault is not stored within google backup and sync „my computer“, but in „my storage“ (or similar, I dont have a EN client)
