Paypal payment does not change membership/VIP membership

[welington]

Previously, payment via PayPal was ok in XF2.2...
Then I updated to 2.3.4 and it stopped working...
I have the same problem, a member makes a purchase via PayPal, but nothing happens for a member/VIP member.
I have to do it manually.
I'm very ignorant about this.
If anyone has a solution, please let me know.
