So it suddenly started working for me. I downloaded the AIP app the other day. I tried the other day, and just now and it did NOT work. Then I opened the AIP app (again for the 10th time) and went back into the outlook app and the wav file opened in AIP and I got AIP as an option along side Adobe for Intune, Wod and OneDrive for opening a pdf.
It seems like AIP will work, just take some time for the apps to figure out that AIP is available?
OK, so I was able to download the app, and I made sure it was included in the targeted apps in the intune policy, but when I click on a WAV file I still just get a message saying there is no app on the device that is allowed to open this content.
How do you open the wav file in the AIP app? I have to company portal app installed, but can't find an AIP app in the play store. When I click on the wav file, I do not get an option to pick an app to open with.
