SfTabView content not visibile after navigating using Shell

[Andreas Reitberger]

Hi,

Since I've updated the SfTabView nuget the content is invisible after navigating away and back to the page where the TabView is used. I only tested it on iOS.

Last working version: 19.3.0.54

Please see the video attached.

I'm using the latest stable version of Xamarin.Forms if this is relevant.

Hi Ruba,

I was able to update the example project to show the issue.

What I did:

1. Added a SfTabView to the ElephantsView
2. Set the ElephantsPage to the first shell item

How to reproduce the issue:

1.  Start the project (iOS)
2. Vertify that the elephants page is the first shown page and the labels are visible (screenshot 1)
3. Navigate to the monkeys page and return to the elephants page
4. Switch the tabs by clicking the tab header
5. Verify that the labels in the SfTabItem is invisible (screenshot 2)
6. Swipe down with the finger and the label gets visible
   

Please find the updated project attached.

Hi Andreas,

We don't have a weekly NuGet release today due to the release of Volume 4 SP, 2021. This fix will be included in our next weekly NuGet release, which will be released on February 8, 2022.
