Hi,
We have an app deployed at the client, where "nothing” has changed. However, something did break. 
According to the client they restored the data Db due to a problem but left the IAM Db untouched. 
After this restore, whatever we try , we cannot grant access to any user. We all can access IAM, but not the app. I've have copied the Db to my testing server and tried a lot.
Deployed a new model. Made a new app. Removed all users groups. Deactivated and reactivated all modules. Reset users.. Did a schema compare to our UAT Db. Didn't show a thing.
In the Tenants overview - In the Current Access, i see.
- Users = x
 - Users groups = x
 - Granted Module = 0 (!)
 - Granted Apps = 0 (!)
 
When comparing with the LAB environment, all settings are the same.
Any pointers on where to look? I would love to know why this ''suddenly’ stopped working and we can't fix it.
Thanks!
Blommetje
