Haven't tested but I found "Story Cutter" app which works very well to crop videos to 15 secs and upload separately.
P.S free version only allows to cut videos at max 10 secs but I found pro version of apk in the Internet.
Can't post second video to Instagram stories. First video of 15 seconds gets uploaded but next videos (if while video is longer than 15 sec) are getting error and are impossible to post.
Haven't experienced this but IG on MI9 has a lot if bugs. One more is that whatching IGTV sides gets cropped or the whole video is zoomed so you can't see the corners while it doesn't appear on stories but this is literally the same size of picture/video.
I've been waitint for like 4 months. I have already left not one feedback about this kind of bug on Google Play and no response or fixes so I think we shouldn't rely on them.
Good day,
Recently I've faced a really frustrating bug.
When zooming camera response is like 0.5 sec. And it's really hard to control. It's not smooth and not pleasant experience.
Any fixes?
