Publish online is a great idea with a brilliant future and I love it. Hope Adobe will continue to update it although I am not so sure. Most major browsers on Safari Firefox Opera Chrome Mi on desktop or mobile Windows IOS and Android, look they r working fine. There are issues with Android Chrome which in some countries is a big issue. (browsing a published document with Android Chrome control bar next-previous buttons appear instantly and then disappear and can't bring them back, touch, zoom seem not to be working either and browsing freezes)
