thanks to the excellent instructions at this address, I managed to copy a profile from an iPad to another iPad, using the latest App version on iOS [1.4.18 (debug)]
However, I wanted to copy the profile also on Android, I have tried to email to myself the profile as an attachment, and clicking on it I was able to open it with the Android App [1.4.29] and import. The strange thing is that for a few times the import just failed, complaining that the format was unreadable. Finally, it worked, I think because I first created a profile with the same name in the App, then I overwrote it with the import action.
Is this behaviour expected? To be honest, I am not 100% sure that it worked for the reason I've stated...
