Hi
I've been using my astro with 5 collars for 6 months without any bother. Iv just bought another 2 collars, European software just the same as the others, but the new ones aren't tracking, their pairing up but wont track. In the box it says to update the astro to the latest version to get them to work, but Im worried that it'll no longer work in the UK. Has anybody else updated their software? My astro is version 4.41 and new collars 2.60 but old collars are 2.20.
