Thak you Willi,
I sent to Avalon a couple of emails but I did not get any reply yet. I have also noticed that the Stargo2 driver crashes when moving the telescope with ekos munt control passing the meridian around polaris and you can only recover it after rebooting it.
One question, do you get reproducible polar aligment manually? i.e, if you PA manually with your workaround and then move your telescope and then you do PA again are you still close or minutes away? I do not why I cannot keep a stable PA.
