I am having issues with installing the IPA files onto iOS devices from the AppStudio OTA service. I send the link to the user that needs to download the app, and the only thing that happens is the IPA downloads to the device and that is all. No option to install or anything. I can log onto the OTA through a web browser from my device and install the app from the OTA portal, but the emailed links do not seem to work. Any ideas for installing these files on iOS devices? Thanks.
