Have you tried uninstalling/reinstalling the app as of yet?
Would you kindly record a video of your screen to show us this behaviour in action and then post it here in this thread for us? If you're not familiar with how this works, you can find instructions at this link: Record the screen on your iPhone, iPad, or iPod touch - Apple Support (CA)
When logged in and composing a post on this forum, you will see a still camera (for screenshots) and a movie camera icon (for videos) above where you type. Follow the instructions after clicking. If you can't see the camera icons, you need to switch to "desktop mode/version" in your device browser instead of the mobile version. How you do that will depend on your device and you may need to look that up on the web.
This issue is only with the recorded videos. Live video looks fine.
I tried to click on an area of the recorded video and also clicked the pause symbol and waited for few seconds. The symbols didn't disappear.
However, when I touched either the bottom or top of the video area for long time and then move left or right, the video is forwarding/back warding with high speed and the symbols are disappearing. But they are coming back as soon as I remove the finger.
Thank you for providing us with those images.
We'll need to escalate this for you in order to investigate it further. Please send a private message to @CommunityHelps so we can get started on this for you. Not familiar with our private messaging system? No worries, click here.
We look forward to hearing from you.
