Hey @Gadg8man. The Ring Explorer’s program is by invite only and will randomly be sent to your email at the time of need for testers. If you have been in the program before, they may be going through the list of neighbors that haven’t been involved first before circling back around, or maybe since you have been in it before, this puts you at higher chances! From my impression, the picking is at random, so make sure you check your email every so often and your spam folder just in case!
