[Bug] TabView does not switch tabs on UWP

Description

Tapping on other tab does not switch current tab. Looks like indicator is trying to move into other tab but it goes back, CarouselView tries to move content but goes back too.

2. Go to Views -> TabView -> Getting Started.
3. Tap on Tab 2.

TabView is switching tab.

Actual Behavior

Tab 1 remains visible.

• Last known good version: unknown
• IDE: Visual Studio 2019 Enterprise 16.8.5
• Platform Target Frameworks:

Any update on this?

We are also facing the same issue. The tab just does not switch.

So folks this is a show stopper on UWP Shell application. The tab just does not switch no matter what you do. Double tapping tab does not make it switch. And I am using the very latest XCT v1.2.0-pre2.

Is there any workaround until it get fixed in next coming release. desperately looking for an update on it.

[Orgbrat]

@techravi007 Have you heard or read something that definitely states this issue will be fixed in the next coming release?

[techravi007]

@Orgbrat No, I haven't any clue if it is going to be fixed in the next coming release though i'm hoping they should fix it.

@jfversluis Well I have never done anything with someone's open source project before, but I have forked the Xamarin.Community.Toolkit repository and I am going to see if I can tell what is going on with the TabView not working correctly in UWP. Not making any promises but at least I do have everything I need to work on UWP on my machine although I am not a UWP expert. But I am willing to give it a shot. Worst thing can happen is that I fail to help the issue... :)

@Orgbrat Thank you! If You need help I hope I can help. We need it too working for UWP.

[Orgbrat]

@Agredo Well unfortunately I have received a new project to work on and my time is very limited for this issue. I will get back to this as soon as I can. But this is an issue that needs to be fixed by someone. Sorry...

this is still a big issue

It seems to be bug of CarouselView as it is placed inside TabView for transition switch tabs

Same problem here. Many times the tab that is shown when you click the strip is a wrong or previous tab
