Hello there, Turkish walker here :)
This issue has been happening quite a lot lately, although my watch is set to "THE BEST SIGNAL" i am not getting any.
Sometimes the watch acquires GPS signal immidiately, sometimes it takes 5 minutes but this time is my record... It is 50 minutes.
I've just updated my watch to v13.22 but there is no changelog about GPS...
Really sad. Is my watch faulty?
