iphone says "Share My Location Disabled" but it isn't
Working on my mom's phone - it's an iphone 7 plus (ios 14.3). When I try to "share my location" on her phone with me/my phone, it says "Share My Location Disabled - Enable Share My Location in Settings > Apple ID > Find My to use this feature". I go to that place in settings and see that it is already enabled. I tried disabling and re-enabling. No luck.
Any suggestions?
Thank you!
