Hyundai Tucsor 2018 Air conditioning question

[yarecky3]

Hi.
Any specialist regarding A/C systems?
I have a 2018 Tucson 1.6GDI. Everything seems to be ok but its still not cooling.
Refigerant pressure when a/c is off is 6640 kPa, when on is slightly changing to 6216kPa. Alla available signals in ECU data are correct (mean on, signals are acivated).
But it still not coling.

Is the refigerant too low in r1234yf systems?
No faults found.

Any sugestions will be appreciated.
cheers
