Strange new issue - Can't get altitude

[Foosy]

Last 2 times I flew my P3P, I had a strange issue happening after taking it out of the case.
When I turned it on, I got a message on my iPad app, something like: "Can't get Altitude".
(I will need to check this again next time to make sure I have the exact message...)
In any case, I waited while it was blinking a purple dot next to the message for quite a while.
Nothing was happening, so after a few minutes of it trying to do something (I heard these sounds...), I noticed that the camera gimbal had not balanced itself, so I nudged it very slightly. It balanced itself and the message went away.

Both times were exactly the same. Has anyone else experienced this?
I must say it did not impact the flight, but I am worried it is an indication that something might go bad...
Any clues?

If you get a message like that ... mhhh may be you have some barometer issue ... I never see it and I didn't even know it exists on the DJI Pilot app. First think that come in mind is an IMU calibration, then a gimbal calibration.
