I have our solution. Right now, I can only do a mobile download where I get prompted by using Safari on iPad. Neither chrome nor FF will work. It’s probably something to do with the iOS ecosystem and saving of files access/security to the root file structure on iOS mobile. But IDK - this could be a follow up for WiX to investigate compatibility and portability. That’s up to WiX. Case logged. But for now I have my workaround.
Oddly enough, I found some restrictions in uploading media from the FF mobile browser, it disallows me to upload a file from any cloud storage connected folder EXCEPT the FF downloads folder. I keep my files on G-Drive. Workaround is to lift/shift files to/fro back and forth. Not ideal.
Will test safari for that soon. Since that oddly enough is the less restrictive browser
