In shared albums, the disable live photos under share settings does nothing. All my live photos are shown as videos for android users in the same album. Disabling live photos for all my photos in the iOS system settings is of course no fix here because live photos is such a valuable feature in my experience, and the setting in the Google photos app should just work properly and not show live photos to others when uploading live photos from my iPhone.
The workaround here is to make a minor edit to the photo (i.e. Adjusting brightness with 1 step) and then saving it. This fixes the issue and android users can now download a photo instead of seeing a video, but this is very cumbersome when sharing 100+ photos.
Would not recommend this for sharing photos while this is not working as intended.
