Is there a plan to update the subscription module to be more compatible with DNN 9.1.1?
I am using the subscription module and the latest version of DNN 9.1.1 is back to using the user, roles and UserRoles tables. 
Subscription uses the aspnet_user and aspnet_Membership tables.   
Here is the issue.
When you use DNN to delete a user from the users persona bar, it removes the user from the user and UserRoles tables.   If you try to create the user again through the subscription module, you get an error saying the user exists.

DNN does not clean up the aspnet_user and aspnet_Membership tables.  The subscription module uses these tables to see if a user exists.

To duplicate  this issue:

1.  Create a use using the subscription module
2.  Delete the user using the DNN user persona bar
3.  Create the user again using the subscription module
