The watch needs updated GPS ephemeris data to accurately calculate the position, received by an aGPS (Assisted GPS) server (over IP) or by satellite. This takes at least 30 seconds by satellite.

Solution: Tether with IPhone before leaving until fix is achieved, otherwise keep watch outside or near a window for 10-15 minutes before running so that it can update its almanac from overhead satellites and get a fix.

There is no software solution. Buy a newer watch with cellular connectivity and aGPS-support.

Do you have an explanation for this being a new issue?

OP could have changed exercise habits, leading to more frequently outdated GPS almanac data.

Otherwise, newer OS versions could have degraded the fix algorithm for older Watch-models.

If newer hardware comes with cellular connectivity, newer OS version could assume that by default and not prioritise (or test) backward compatibility with older Watch-models.

Why it would need such common updates tho ?

And why it couldn't load that data for say month ahead ?
