Compass Calibration Error

[la.batman]

I just updated to Open Solo 4. Im now getting a Compass Calibration Error, Use the mobile app. When I select compass calibration I get another message that tells me that I need to be connected to Solo. Im already connected or at least I think I am. Ive repeated this several times. Can someone please advise? Thank you!

Try using Mission Planner form a laptop.
Has done it for me in the past

A few days ago I updated to OpenSolo4 and I have the same problem, I use Solex to calibrate the compass but it gets stuck in the middle or sometimes it manages to finish the process, but when I restart SOLO, the compass calibration message appears again, today I spent 3 batteries just calibrating the compass and I couldn't fly.
Another issue is about the missions in QGC, if I manage to fly... it does the mission flight but GoPro doesn't take any photos... Uffffff.
Tomorrow, I will return to OpenSolo3, since I had no problems with it.
