Iblinds v3 calibration issue

So finally got around to installing my iblinds v3 (well one so far as a test). My issue is calibration. upper and lower tilt points just don't seem to work no matter what I do. Using 3.11 firmware.

Press button 5 times, wait a couple of seconds, press one more time then send open command.

Unit goes through calibration and then most times close is open open doesn't close all the way. Change start position in driver to close and save then configure then hit open or close and work normally but tilt points are still wrong. (closes at like 20 percent, opens not much after that, maybe 35 percent)... Any of you have issues like this before?

Yes.

@Hal3 It was solved by firmware update and the calibration
