I couldn’t see Tower nor ATIS frequency even though the controller sent me on guard. Luckily the controller let me proceed my landing via the IFATC slack. When arrived on ground I could contact ground but still no sight of the two other frequencies. I then proceeded to close the session ( without a app reset ) and re spawned and just like that I could see all three frequencies. Weird… and apparently this is not the first time.
Screenshot was on ground.
