Some good news to report - so far I have done more imaging with v3 and ran several plans without issue. I have a asi294mc, zwo focuser and filter wheel. Asi220mm guider. Am5 Mount. Fra400 scope with reducer running f3.9. things I tested: guiding, focusing, filter change, auto focus in temperature change, meridian flip, preview target search and goto, several multi object plans. It all worked well. I did not attempt allsky polar alignment however. There is just one change I noticed - I could not add objects to the end of a plan while it's active but paused. I thought I could do that in the past but I could be wrong - you know age issues :-)
Suggestions: It would be useful to allow adding objects plan in process without a reset as long as it's paused and after a current object
