Hi There,
I'm in the same boat, where I need guest apps to show in the powerapps mobile version.
My reason: At the time if this reply my app requires the ability read information from a QR image from a tablet or mobile device. Short version, the barcode for web feature is depreciated in the browser and only seems to works for normal bar codes but not for QR codes. Doesnt pick it up.
But there is a way to get the guest app to work in the powerapps mobile app, Yeah!! 🙂 . Its odd but it shall work.
Tested on an android device
1.) Share the app as per normal process for an external user.
2.) Make sure powerapps is installed on the mobile device.
3.) Advise the external user to open the email from the mobile and select "open app". It should prompted them to either open via the browser or powerapp, Choose "Powerapps" of course.
4.) Sign in as per normal and there you go, it'll open in the powerapps mobile app.
5.) Swipe to the right, refresh your app list and you'll see the guest app in the list but all your other apps will disappear if you had other apps. Dont worry that's the "Odd" bit. Lets continue..
6.) On the gust app select the 3 dots or ellipses (not sure what its called) and pin the app to the home screen.
To get back all the other apps that you might of had, close powerapps mobile and reopen it (not using the guest app icon on the home screen).
Play around from there..
Really hope it works for as it works from me. Its odd but I'll take it.
