I opened Listen Later from the menu. The list is empty because I haven’t added items yet.
I selected Filter at the top and the input box appears with the blinking input prompt. When pressing the back button twice the app freezes. I have to force a close and restart the app to get it responsive again.
Edit:
I just found out: the problem also occurs when the list contains items.
Thanks for reporting!
Could you please specify the Device name and Android version?
It would also be great if you could record a video of the behavior you were facing.
