Solved: Problems with New mobile framework

sanchezvjc43

I would like to know if the new AppSheet 'New mobile framework' feature causes issues on certain phone models. Some devices show the app as blank, and I'm not sure if it's a configuration problem on my end.

Here’s what’s known and what you can do:

Known Issues with the New Mobile Framework:

1. Blank Screens or Crashes:

Common on older Android phones, especially those with low memory or outdated WebView components.

Some iOS devices may also show blank views if animations or transitions don’t render properly.

2. Slower Load Times or UI Freezing:

Some users experience unresponsive buttons or long view load times.

3. Component Display Bugs:

Buttons may disappear, formatting rules may not apply correctly, and forms might not load as expected.

4. Intermittent Behavior:

Works on some devices but not others — even if same OS — due to things like:

App cache corruption

Browser rendering engine differences

Screen resolution handling in the new layout engine

What You Should Do:

1. Turn Off the Preview Feature

Go to App > Settings > Preview and toggle off “Use new mobile app framework.”

Then republish and test again.

2. Test on a Copy of the App

Create a duplicate of your app.

Enable the new framework in the copy only.

Test on various devices before rolling out changes to your live version.

3. Use AppSheet Monitor

Go to Manage > Monitor > View App Log and look for any runtime errors on affected devices.

4. Report to AppSheet Support

If the issue persists, open a ticket with AppSheet support and include:

Affected phone models

OS versions

Screenshots or screen recordings

Your app ID

Temporary Fix for Users with Blank Apps

If some of your users are already stuck with blank screens:

Ask them to clear cache, reboot the app, or reinstall the AppSheet app.

Have them log in via a desktop browser temporarily, if available.

It's always possible that issues occur with any new feature. Try turning off the Preview settings and see if your app behaves correctly then. If the app still shows blank then it is likely something in the app definition. If you continue having problems then post back here with more details about your issue OR contact AppSheet support for assistance.

FYI, it is strongly recommended to NOT turn on the Preview settings in a "live" app. As changes are made, they can destabilize the app. You should use the Preview features to test them in a safe test environment. For example, make an app copy and then turn on the Preview Features in that copy to try them out and see how they affect your app.
