Square app won’t open at art show now help?!?!

[Jess6]

Help!!! At art show now and app won’t open for credit card sale. I touch it it try’s to open then it goes to home screen on my Apple I phone 6. I have not used it in a month but had no trouble using for always all summer long for shows!!!

Does the app need to be updated? Restart your phone and try again? Delete and reinstall the app? Hopefully one of those will get it working again.

It happened to me as well. Yesterday was fine and today my screen locked and wouldn't allow me to enter any charges or switch to my dashboard. I have deleted and reinstalled the app. I can't open the app now because typing locks before I can enter my entire email address.
