There has been a report of a recurring donation profile being created on a supporter's profile in "Pending" status. It is unclear how this recurring profile was created, and the monthly donation cannot be cancelled.
The pending profile was triggered with an unpaid $10 donation. A control panel user accidentally paid the donation in an effort to delete it, which he believes to have charged the supporter through PayPal Express - though this charge has not been confirmed.
We have not been able to replicate the reported behavior so please comment below if you are experiencing a similar issue!
If you require any data cleanup due to this problem, please email a link to the relevant profile to firstname.lastname@example.org.
