The other night I was trying to Polar Align with my guide camera, an ASI290mini at F4. It went well, plate solving and determing a solution for me to work with. Then after several "Refresh" images that resovled, some that didn't, the error came up. {bug?}

"Could not determine mount position."

This was the end of it, the process stopped. I tried several more times and the same failure. Then I switched from the guidescope to my 8" EdgeHD at F10
You may think, as it was pointed out to me later, that I went from easy plate solving to hard. (I was thinking more light, more stars.)

The exact same thing happened with the longer focal length. I got very close to finishing the overall process,only needing to adjust the mount. I did 2 or3 adjustments only to end up with the same error.
I would say the seeing was poor. Transparency is something I am working on understanding in relation to my location. I will say this night was a better one in terms of how many stars I could see nearer to the horizons, but the sky STILL did seem washed out. In other words you could see the bright stars but little besides that. {seeing/transparency?}

Question is: would unchecking "Use Position" have let me continue? {setting?}

Thanks
