Apple App Store Not Letting Me Download Matchpub App On iPhone

"When I try to log in to the Matchup app with my Google account, I get the error "There was a problem signing in, try again later" and cannot access my account. This issue started very recently and this is the second time I've encountered the same error. I contacted the Matchup support team about the problem I'm experiencing and was directed here to submit my complaint. Nevertheless, I still cannot log into my account or use it. I request that I be able to access my Matchup account again without issues and that my login problem be permanently resolved."
