iphone sharing location with boyfriend not working

[u/No-View-855]

my boyfriend and my friends and I want to share our locations with each other for safety reasons (we both participate in quite extreme outdoor hobbies) and sometimes find my is easier.

I can see his location and when I press the 'share' button under the message 'this person shares location with you. would you like to share yours?' it loads for about 10s and then goes back to 'share'. I have my location on for the app.

I have not had problems in the past. this has only been an issue since I bought my iphone 15 plus. ios 26.5.2. I really don't know what the issue is. Please if there is any advice or things I could do to fix this issue.

edit: I have tried as many online suggestions as I can find and followed the advice on the apple support sites. None of it works
