I compiled a release version of my Xamarin Forms app (android) to give it to my client (adhoc). He tested it and everything worked fine.
After some more code added, i published another adhoc release to give him. I changed the version number and used the same keystore.
He was unable to install it, even after removing previous version. As if there was some traces of the last install messing around.
Did someone ever had the same problem?
