On my 2020 319MLOK, I had issues at first, and still do a bit if the ground is too out of level. I have the tablet inside, the app on my phone, and of course the controls in the basement. I have found that I have much better luck with the auto level by getting the unit somewhat level front to back with a small bullet level sitting on the edge of the basement in front of me and then using the auto level on the control in the basement. The biggest frustration I have, is the system seems to keep lifting the camper to achieve level and that sometimes lifts one side's tires off the ground a bit. I end up manually dropping all jacks the same amount to bring it down after auto level is completed. I don't understand why it can't bring the jacks up and down to achieve level.
I had a similar issue after the firmware update- found out my rear jack cables were reversed on the module in the front bay.
As already mentioned, I also had issues with letting out “too many holes” with the front jacks- it was nose-high. I stick to 9 holes and haven’t had an issue since
