Can't log into Soundcloud in Rekordbox on IPad suddenly?

Hi - hope you can help?

Suddenly I can't log into Soundcloud in Rekordbox on my iPad. Was working fine until 24 hours ago. I've updated all the software, ios 18, and latest version of rekordbox. When I try to login via apple id it tells me to enable pop ups (which I've done) and then just "cycles", when I try to log in with my email it doesn't recognise my email/password. When I ask it to send a link to reset the password I get an error message repeatedly.

There isn't an issue with my soundcloud account - I'm logged in via their app and via chrome.

Thanks in advance if anyone can help?!
