Johno_efc How does one go about getting access to the beta?
Which beta?
If it is the beta for the v1.6 ASIAIR app/firmware, you need to first download the TestFlight app from the Apple App Store. You then go to the iOS link that is shown right at the very first article in the ASIAIR Facebook page to join the beta testing program.
I recommend that you avoid the beta unless you are familiar with ASIAIR and iOS, and if you are willing to provide feed back to any anomalies that you have discovered (your email address and IP address will be sent to ZWO and servers in China).
