Also I tried to log via web.monzo.com and the page freezes and does nothing (I tried in Safari, Chrome and Firefox), however I can still access fine on my previous phone.
Have you tried deleting the app on your new phone and re-downloading it? I think if you do the migration from one phone to another it can get messed up and this seems to fix it. Won’t hurt to try.
Thanks for the response, I did it both with wifi and cellular connections, apparently it was some problem with Monzo authentication/login services, since I tried the same right now and it worked.
Ah, now it makes sense. At the time this wasn’t known about but it was a Monzo issue with chat and login problems yesterday evening. The ‘different phone’ variable was a complete coincidence.
