Trouble Logging In

I reinstalled the app today to try and order a card and when I enter my phone number I get ‘something went wrong, please try again later’. I reinstalled the app but still have the issue, sometimes I get to the page where I can enter my passcode, sometimes I do not.

I have forgotten my pin but when I enter my phone number and hit next to reset the passcode, the loading screen appears for a while but then returns to the page where my phone number is requested. Can you help me out please?

Thanks,
Graham
