After changing cellphones to a Pixel 6, I don't seem to be able to login anymore. Every time I try to log-in I get an error message saying "A technical error has occurred. Please try again later". I know my password is fine because I'm able to log-in in their webpage, and in their webpage they're not providing any way of contacting them digitally (just phones) -- which is annoying.

Total disaster.. after updating I need now to register my device (phone) again.. and as I have separate phone for banking with limited connections and apps installed now I need to repeat the whole circus of removing sim card from the other phone and putting into the "banking phone" just to confirm the sms... Do the devs have no imagination and not tested different use scenarios? Appalling..

I am using this app with CUMULUS on my Galaxy S24. For confirming a purchase with the Credit Card I am requested to confirm pressing the button on the right below. Unfortunately this button is right u n d e r the low line with Android control icons. Please move your button more up, the way it's now does not work.
