Hi Illaya,
Deleted the blue folders for iOS and Android in source tab and did undo all source changes on the root directory. After that tried with new database by removing older database. Still, the device registered (push notification) is not working. Please advise.
Kind Note: There are some blue files under Web Resources folder in the source tab. If we delete this folder, all pages and the styles sheet will get lost? Is this folder too need to delete and undo all source changes?
