ARBs not autorecurring in CB

Once I process the manual renewal and change the dates, do you think they will resolve themselves and reset to auto-renewing once their ARB processes again via Authorize.net and the completed transaction is posted via silent post?

I've no idea, if they have an auto recurring subscription inside of Authorize.net still then would assume you'd get a renewal notification and their subscription would renew as normally.

Okay. I'll let you know once an ARB runs that has expired. One more question...

I have 2 subscriptions that were due to expire today and ARB would run tonight. They ended up expiring today in CBSubs before the renewal / ARB took place. Do I need to set each plan to have a 1 or 2 day grace period before they actually expire to allow time for ARB to process in the evenings? I was expecting the ARB to process tonight and then the plan wouldn't have expired at all, but it expired in the middle of the day instead...

Thanks,
Linda

ARB doesn't trigger the expiration. Subscriptions expire when their calculated datetime is reached unless payment gateway sends a notification before or right at the time to renew. You should have at minimum 3 days grace period to allow time for notifications to reach your site.
