Describe the bug / error

We have a couple SPFX web parts that work just fine on mobile browsers (see images below) When we try to use the SharePoint Mobile App, both Android and iOS, they just wont load.

Is this a normal behavior? Are we missing some "setup" to make them work fine?

Steps to reproduce

1. 2. 3.

Expected behavior

SharePoint Mobile App would show the custom spfx web parts correctly

I am experiencing the same problem, both on Android and iOS. Mobile browsers still work well.

I also have the same issue; SPFx solutions with 3rd party API integrations are not rendering in the Microsoft SharePoint App on iOS or Android. In Safari and Chrome browsers they render as expected. The issue is only when using the "Microsoft SharePoint App"

After further testing I have narrowed the issue down to token acquisition when using the AadtokenProviderFactory to get a token to call our API, From my findings the getToken method stalls and never returns the token or throw an error that we could catch, I also tested just trying to get a token without calling our API and got the same result,

As a quick example: private async getToken(): Promise<string> { try { this.showMessage(Start getTokenProvider....); const tokenProvider = await this.context.aadTokenProviderFactory.getTokenProvider(); this.showMessage(Start getToken...); const token = await tokenProvider.getToken(AppSettings.clientId); this.showMessage(Token aquired...); console.log("Token: ", token); return token; } catch (error) { this.showError(Error in getToken: ${error}); } } The "Token aquired..." message is never hit and no error is displayed either so we have come to the conclusion that this is where the issue is.

This is the case for all our spfx solutions regardless of version as we have various solutions using different versions including the latest v1.18.2

Still no answer and app still wont work on some tenants for SharePoint Mobile App.

When can we expect an answer?
