I had this exact connection situation in November and we were ~25 minutes late departing ORD. Upon arrival in LIS I
checked the app and found out I had been rebooked to the later LIS-MAD connection. They had new boarding pass
already printed at transit desk area.

We landed at a remote stand and lines were not long, but I tried to rush through and get to the gate anyways, and the
plane had already pushed back.

So if you're delayed even by a bit, be prepared for the alternative. Good news is that EC261 might be applicable in this
situation.
