Hi Alex,
Yes all conditions set up ok, though I’ve just discovered from the Lancaster Uni Aurora Watch website there are two (both third party) Android apps using the Lancaster data, titled AuroraWatch UK and Aurora Watch UK. I was using the former which has the same (green wavy) logo that Lancaster use on their website but I see on the internet page for that app they acknowledge that there is a problem with a google play limit on how many free alerts they can send out which I guess they quickly exceed these days with the increased interest. I have now downloaded the app with the space in the title (which has a green spiral logo) so hopefully perhaps that is more reliable. Is that the one you have ?
Cheers
Robin
