My Question or Issue

I made my one-time payment (1 month) using Momo.

The transaction in Momo was successful (my Momo balance was subtracted) but when I was redirected to live.adyen.com/hpp/completeMomo.shtml, it said

Invalid Request
Unfortunately we were unable to process this request

 The page also showed a 'Previous' link but it did not do anything.

I have just received an email from Spotify notifying the payment was successful (about 15 minutes after the payment).

Looks like my account is Prremium and things are working properly now.
