Yeah, it’s messed up, huh? I don’t have a Cam OG Telephoto myself, but I would’ve expected it to display like the Cam OG’s timeline. Thank you for confirming that. 
I like the way you explained your reasoning for this. Like one example could be spouses who share the same login credentials because of Wyze’s limitations with shared access user permissions, but one person uses 24-hour time and the other person uses 12-hour time, so the camera time stamp in that scenario would be flipping back and forth depending on who last pulled up the stream in the app, because both users are essentially using the “owner” account, right? That is if the time stamp followed the user’s phone setting. Yeah, that would be a disaster. Good point.
Note that I’m making a distinction here between the time stamp overlay that’s incorporated into the video by the camera itself (via setting on the phone) and the timeline that’s displayed on the phone screen by the app during playback. (I think it’s important to mention that and be clear about it because both seem to be discussed in this topic.) I think the app could be written to account for an individual phone’s setting and adjust the playback timeline for that viewer’s preference (just adopt it from the phone OS’s setting), but the time stamp should be set via an app option in the owner’s Wyze account (I like @Loki’s suggestion), and that format should remain static according to what the owner manually selects.
Absolutely, and this should be an owner-only permission setting (and then Wyze should do some meaningful work on shared access user permission provisioning).
Thanks for adding more detail!
