Hi, I created a canvas power app that connects to some SharePoint lists. I shared this with my external account to do some testing. If I go to the web link on a browser it works fine. However when I download the PowerApps app on my iPhone it doesn't work with the external account. When I try to sign in it tells me to use my work or school account and gives me a session ID.
The iOS PowerApps app does work with my regular work account and the app i created works fine as well, it's only when trying to sign to the iOS PowerApps app with my external account.
Any advice?
