Good day! I have a trip coming up with Swiss on an AC ticket. Today when I was checking my itinerary I noticed this:

There doesn’t seem to be a link to further details, and the flights are all showing confirmed and on time (today is only T-3.5 though). Interestingly enough, this only shows on the mobile site. The Swiss app or the full pc site do not indicate this at all, and nothing shows on AC’s portals either. This is my first time seeing this, does anyone have some better insights or experience on how concerned I should be? Thanks for your input in advance!
