Please attach a sample project that reproduces your issue.
Note that ViewPager and FragmentPagerAdapter have been deprecated.

Yes, issue is fixed when upgrading to ViewPager2
il...@google.com
Glad ViewPager2 is working better for you.
If you'd still like us to look at this particular issue within FragmentManager, we'd be happy to re-open the issue and take a look at a sample project.
