Describe the bug / error

I have a SPFx solution that has 4 web parts in it. I have created a teams manifest that creates a tab for each web part. In Teams Desktop on Windows and Mac, on Teams online client, and on Teams on Android mobile all four tabs load their SPFx web parts, however on iOS mobile and iPadOS only the first 2 tabs load. Tabs 3 and 4 give the following error message on the screen. Unfortunately, this makes the application unusable for the mobile workers.

Steps to reproduce

1. Build an SPFx solution with multiple web parts
2. Create a custom tab for each web part.
3. Deploy to teams and try and load on iPhone or iPad Teams.

Expected behavior

Tabs 3+ should load the SPFx solution.
