Hey manu ,
Thanks for your patience!
We've been in contact with our payment handler and we found out that there is an issue in the renewal/update payment checkout.
The renewal required an additional
authorization step (requested by your bank, such like 3D Secure) which should trigger a popup for additional authorization (for example, accepting the payment throug your banks app). However, this was not being triggered by the checkout when renewing.
It appears that the authorization step is working properly on the 'normal' upgrade checkout. This is the reason why the checkout worked.
We hope that this issue is fixed soon so that won't happen again. I hope this explains it all, I can ensure you that it wasn't a trick and was not intentionally!
If you have any further questions or additional feedback, make sure to let us know 🙂
