So I put in my old SSD micro card but when I went to the app the message was there is new Firmware and nowhere to bail out. So I had to go with the new firmware again. This time tracking was not good, but the above issue was only present on one sub. I had covered my rig, so that everything was the exactly the same except I did PA again. definitely puzzling. back at home now but clouds for a week. I have to perform guide calibration more than previous version, in fact every time I switch targets or flip now. Also, an old issue of guide stars migrating upward has reappeared (which was fixed in last version). to fix I close the app and reopen, that seems to fix most of the time.
