Membership + Paypal + Coupons not working

I see the threads that it’s a known issue that coupons aren’t working and the beta fixes it. I am wondering if #1. anyone has a work around for this so I can safely offer my coupons and #2. when the fix will be release or #3. if I install the beta version that has fixed the coupons, is everything else working and will all my settings and subscriptions and members show in the new version?
