Yes, the GAGB one went live last night
I think the only way to find out if they’ve been published is to keep checking the app. The ‘Welcome to Devon’ one looks good, as there are physical containers as well as virtuals (most of the ones on the app so far are just virtuals).
One problem with the virtual ones is armchair logging. I heard the Nottingham one was completed by loads of German cachers as some of the answers could be found on Google. They’ve since tweaked it, and Groundspeak have retired the web player, so in theory it should mean that it can only be completed in the field as you need to be using the app.
