unable to sign into Meijer app

When I try to sign into the Meijer app on my iPhone 13 with iOS Version 17.4.1, I get the following message: Sorry! Looks like something went wrong on our end, and we couldn't ...

"Try again" gives me the same result. I went to settings, iPhone storage, searched for the Meijer app, offloaded and reloaded the app; then tried the "delete app" option from that same location and reloaded the app, tried shutting off my phone and turning it back on. None of these resolved the problem. I spoke to a Meijer representative and she did not have any additional ideas other than to contact support for the phone. This is the only app that is giving me problems. Any other suggestions? Total storage of phone is 35.13 GB used of 128 GB.
