I have the problem that vimeo permanently in the background continues. Every time I open the background activities it appears again and again. I have a huawei p20 Pro is it possibly on the phone?
Does the video appear as a small window?
If so, the feature is called picture-in-picture mode and has been part of Android since Android 8 (is installed with you).
There may be an option to disable in the Vimeo app.
Otherwise you should be able to revoke the authorization via Android. Dursuche to best the settings of the device after picture-in-picture mode. It may be hidden under apps or app permissions. Maybe the option for this app can also be changed in the app info.
I have the same problem but did not install the app.
Just happened to come to the page today and since then I can't get rid of them.
You have to install the app from Vimeo and then uninstall it, then it should be gone again.
