Because it is PayPal related, I'm guessing it is related to this bug...
This thing work really bad.
Before have this problem and after update to 2.3.3
Suscriptions not work properly.
I just tested the profiles with subscription and xenforo has invented the subscription.
My subscription is a 12 month annual plan for 66€.
However, when I make the payment on PayPal, it creates an item “
My First plan”.
And it charges 6 euros per month with 1 month free? who said that this must be so ? There is no trace of this on my xenforo forum either.
I only found out thanks to the email sent by PayPal.
Something as important...
I had to revert to legacy PayPal because PayPal Rest doesn't work for some recurring subscriptions.
