We have finally fixed the issue with not being able to login and post comments on our Cuckoo for Coupons app on iTunes and Android and Windows phones.  You may need to exit out of the app and go back in to see the new updates.  If you are still experiencing any issues, can you post them below with what type of phone you are on, and screenshot them if possible, so we can fix them? Thanks! We are hoping all the issues are resolved.
