I am getting this error page when viewing the VF page on a mobile device (both IOS and Android) after logging into the Community. It's not a FLS Permission Issue because the page works flawlessly on Desktop following the exact same steps. The Community User Profile also has access to the VF Page.
Any ideas on why this is happening or how to resolve for mobile?
I have already validated the following: Setup > Visualforce Pages > navigated to the page in question > Security > validated both Community Profile & Community User Profile are enabled. I also validated the page has the checkbox for 'Available for Lightning Experience, Experience Builder sites, and the mobile app'.
