Pogo app sync issues

First of all, does Pogo not have its own community here on reddit?

Secondly... been trying to sync up my walmart account and starbucks account to Pogo, but keeps coming back with credentials issue. Went to both apps, logged off and signed back in to verify I was using the correct username and password, even went as far as changing the passwords on both apps... still giving me syncing issues. Anyone else running into the same issue? Or know of a fix?
