I have read through literally dozens of suggestions concerning this and also the documentation related to Powerapps and their tables but due to Powerapps being a moving feast over the past few years none of the solutions help.
I have a new user who is trying to access my PowerApps and he is the ONLY user who gets this problem. With one app he gets the above error and it details a specific table, with another app he gets a Network error. As they both relate to data access in some way I am thinking the root cause is the same as both apps access the same table. Please help, I am at my wits end with this one.
