Good Sunday morning folks. I just successfully checked in to our flights for tomorrow evening, YUL-LIS-FAO. Was able to print and email both boarding passes, passport info is there and correct, etc. But on the last screen ("complete check in) I got this message, in red:

Regulatory data missing. Please go to a check-in desk to print your boarding passes.

Any guidance on what that means? I am a little gun-shy as my last flight in April (YHZ-BNA) I got a "print your boarding pass at checkin desk" message and I got the dreaded SSSS. I reeeeeally don't want to get that again, but if it's coming I'll pack accordingly so when they poke into everything they won't leave me with a disaster to clean up.

Ok, extra weirdness. On printing our passes, they state seats (13D and 13E) but on the pdf they sent us the seats are blank. Is this normal for TAP? I just verified that the seat numbers are showing in the app too, so maybe the blank on the other doc is just there to raise my blood pressure this morning.
