Unable to make purchases

I have bought some plants with money a few years ago on my old phone. I got a new phone a while ago and transferred my PvZ2 account in there. I got everything back, along with the purchased plants. But there was a problem I keep dealing with: I get this annoying pop-up whenever I start the game and when I enter the shop it says "restoring purchase" and immediately goes "unable to complete purchase. Please try again" This is a problem for me because whenever I want to buy something from the shop it keeps popping up and until I get the problem solved it's just gonna block me from buying things from the shop. What do I gotta do to get rid of this?
