This is a longstanding issue that wheelmap knew and promised to solve.

Some info from the OSM talk mailing list.

Use Newpipe. It plays youtube (and several video sites’) videos without any ads nor trackings. No Google account needed.

Install it and set it as the app for opening youtube links in system settings.

Note that the app is not available in Google Play store. It can be installed from f-droid, or you can directly download its apk.
