"The permissions on the editing of the old question groups is not working and i have added a permission for the loan approval where i set the maximum approval amount to be 5000 USD
and it isn't working well either"
Permission for limited loan approval isn't working, but i can't reproduce bug with editing old questions.
Issue with question group permissions is continue in sub-task
Fixed in commit 054e9e133aaef7e455c357408b733f307bf74dad
Permission with max loan approval is now working properly. To the note. Can change state to Approved MUST BE marked if in this role is max loan amount marked. Without that user still can't approve loan.
If max = 5000, then user can approve loan with x < 5000 amount
