Hi Andreas,
wir haben das gleiche Problem.
Auch ein neu Anlegen der PayPal Credentials hat keine Lösung gebracht.
Kannst du uns die benannte Test Datei senden?
I want to use some additional webhooks, but however, the webhooks which always was working, from now doesn’t work either.
I just want to call a simple website for testing and sending any emails for testing. Also the plugin “simulator” doesnt work.
