Is there any way, where Payplan restrict user to create just one Subscription per Plan ? In case, user tries to create another Subscription, then Payplan should auto-redirect to already existed Subscription order.

I guess, that will display error message if user exceeds limit set. Does it also show custom message or url redirect for existing Subscription ? If not can you add redirect url / custom message.

You can use Limit subscription , here set limit to 1 and status to no-status.

What we need is extra clause in Payplans Cron Email Plugin to check whether plan in the category is already active or not. If active, it should not trigger Cart Abondonment EMails for dummy Subscriptions. I guess, this will solve our issue.

 // check user already have active subscription of existing subscription or not

			 $user = $invoice->getBuyer();

			 $userSubs = $user->getPlans();



			 $userPlanIds = array();

			foreach ($userSubs as $sub) {

				$userPlanIds[] = $sub->getId();

			}



			 $subPlan = $subscription->getPlan();

			 $subPlanId = $subPlan->getId();



			 if (in_array($subPlanId, $userPlanIds)) {

			 	return true;

			 }
