Twisty Timer is a material design twisty puzzle timer for Android. It uses the TNoodle library to generate scramble sequences for all current official speedsolving puzzles.
There is a problem when selecting one or more times from the times list, switching to a different page (timer or stats), and then coming back to the times list.
To replicate the issue:
Go to the times list
Now select one or more solve times from the list (long press)
Switch to the timer or the graph page
Go back to the times list
The selection is still visible but the "# Selected" and the trash icon on the top aren't showed anymore. You can still select other times and deselect already selected ones but the top bar won't change.
