I have been, originally Abbey and later Santander personal account holder for decades. The Santander banking App was the only one that I considered secure so have been using for a few years on a MotoG5. Recently I upgraded to a "Redmi Note 10 Pro" running Android 11 and installed all the apps. On trying the app I could not logon with my personal ID. However I can logon with a web browser using it. I then uninstalled and installed again with no success. Get the same message that something went wrong so it looks like the logon does not actually start. I can logon using a web browser from the phone with TFA. I have looked on the Santander website to see if there is anything regarding this or removing the old phone or setting this phone to use the App but cannot find anything.
