Ridiculously slow GPS

Hi All,

I'm sure it's something simple!

The first few runs I did, the GPS was very quick to pick up.

Friday, it took over 10 minutes and in the end, I gave up waiting. So went out running only to find unlike my old FR230, it didn't pick up the first mile - so another 9 minutes to find GPS = 19 mins

Yesterday, I waited for 20 mins - still nothing. I came in, uploaded my 3 activities, ensured the watch didn't need any updates, wiped the activities from my watch and tried again

Another 10 mins, still no sign. Gave up and headed off.

Got to say, for a £300 watch, am a bit annoyed. Already had one issue and had to delete files to free up space.

Any help would be very much appreciated. I've always used Garmin and loved the products but for a more expensive watch, it seems to be problematic!

Thanks
