Yeah, there was some discussion above. (On mobile and hard to scan... ) As far as we know the only option the SC has is the current release (whatever that is). Unfortunately.I was at the service center 6/22 and asked for 2018.24 because I hadn't gotten it yet and he said they were back to 2018.21.9 because of some "glitch" and it was recalled after only a few hours. Apparently 24.1 fixed that (he wouldn't say what the glitch was)
24.1 appears to be rolling out well normally (not the go go go of 21.9).
