I am running v1.84 and with the following issues the plugin is not usable:
ISSUE 1: Selecting the Buy Now button processes at PayPal as Pay Upon Delivery a 14 day delay.
ISSUE 2: Wrong description value passed to PayPal
Snapshots here: https://developers.oxwall.com/forum/topic/52379
ISSUE 3: Membership does not expire based upon plugin settings values.
I tested by signing up on my site for a membership on Jan 12th that should expire in 2 days. I checked today Jan 16th four days later, and still shows the role in my user profile, and on my premium Account status page.
Thanks!
