Issues Using Pogo App

For anyone who uses the Pogo app - I am having some issues with this app.

Every time I try to link my WalMart account, I get an error message. Username & password is correct, so I’m not sure what’s going on there.

Also, I use a PayPal debit card for most all of my transactions, but it’s not allowing me to link my PayPal account either. Not sure how to fix this, or if I even can. But if not, this app is gonna be pretty much useless to me.
