Alternative to Curve?

Does anyone have an alternative pay app to Curve? Ever since trying to use them I have only had trouble, like:

KYC not working on e/OS,

The app making a mistake/failed payment and then my account being blocked for suspicious Activity, saying they would call me and then didn’t.

Helpdesk being slow and unable to help with KYC (took them weeks/months between emails only to say it is impossible to verify me at this moment, even though it worked once before on my old android phone)

So basically I have given up with Curve and am looking for alternatives.

I possibly found another app, and their privacy rating on the app lounge seems fine. But I can not find any reviews or expierences with it. So I am not sure.
