As per other posts, we are still having an issue with PayPal payments not being recognized or processed by CBSubs. Maybe 1 out of every 5 subscriptions that pay via PayPal are not triggering properly in CBSubs and we cannot find any kind of consistent pattern that would help us to understand the cause. In these cases, the payment transaction is successful and the payment basket shows as completed and the subscription is active, but the membership plan activation actions are not being triggered. None of the settings and data modifications for a new paid user are being carried out. To compound the issue, it is very difficult to manually activate the subscription when Community Builder/CBSubs shows the subscription as active and the payment basket as completed, but the user is not enabled, has not been assigned to the expected user group, activation email is not sent and the other plan integrations have not been triggered.

CBSubs is version 4.5.2+build.2021.06.25.17.09.42.53205149f
