Latest 20.22 version has affected GPS accuracy

Is anyone else having issues with the latest version where the GPS accuracy has fallen off a cliff? Well actually it started with 20.16 but watch updated to 20.22 a couple of days later so I thought maybe Garmin were on the ball. Unfortunately not.

I do alot of walking with the wife. She's got a Venu 3s. For last 14 months the distances have been pretty close maybe a max of 0.1 miles difference. I looked at the distances on the same trails when I used another tracker and distances were similar to what i was getting with my Epix Pro before 20.16 came out. Now though the difference is considerable. On a 10 mile walk mine is showing 0.8 miles LESS than hers and it gets worse the longer the distance. I've checked on other watches its definitely my watch AFTER it updated to 20.22. Before it was fine.

Contacted Garmin support - very painful experience - and their verdict "ah its GPS drift and that discrepancy is acceptable". That's not GPS drift, that's a continental shift!! 0.8 miles out in 10 miles. Over 1.6 miles out in 20 miles!! I could be in another town at that distance!!

I've seen a few hits where people have had issues but Garmin thinks its not a big problem.

For a £700 watch, that is pretty damn crap.
