My workout route from the workout app on my Apple Watch 3 is no longer showing on the activity app on my iPhone.

My workout route from the workout app on my Apple Watch 3 is no longer showing on the activity app on my iPhone. 11 Pro Max. Only the starting point shows. I have followed all the advice and have turned off and on all location settings. I have turned the phone and watch off and on and have unpaired and repaired the watch. Any suggestions? I am using the latest IOS versions.
