Wish check out will not processing Paypal

Description

I’m new to wish but have made over 30 transactions from the app using paypal to checkout. After I requested a refund for a "limited quantity deal" it no longer accepts paypal as my payment type. It has me login and it seems like it’s going to work. Then prompts the it couldn’t process paypal payment. I’ve reset the app and the phone and still nothing.. Anyone had this problem and/or know how to fix it? Thanks
