Your feedback has been heard. We already had plans for something similar to this, hopefully we’ll be able to deliver it in one or two version updates.
Unfortunately, LeiaTube can’t talk to YouTube and tell it to pause, so if you have YouTube Premium and Background Play enabled, it will work this way. You can disable Background Play or learn more about it here:
You can also just pause the YouTube video before you share it to LeiaTube.
Or instead of sharing directly, what you can do is pause the video in YouTube first, hit share but instead copy the link to the video, switch to LeiaTube, hit the “+” button, and paste the URL there. That will make it work instantly.
So as you can see there are a few options here.
This is controlled by the Android OS, we did try to see if we could improve this and found that we couldn’t. Though you can adjust the “More” option a bit to your liking, you can’t modify the default share menu.
