Narrative:

We waited over 35 minutes for an aircraft swap due to a broken lavatory. Once we got a new aircraft; the cabin was very hot. We took several minutes to let the aircraft cool with the APU. My first flight with the first officer. I had been off for two weeks (due to covid); so I took some time to get all set up and start with solid crew briefings for fas and first officer. During pushback; flight attendant called to say the banner on the aft door snap was broken. She told me that it was no big deal right now and I assumed I could look at it upon arrival into ZZZ1. The aircraft was terminating in ZZZ1. During the flight after thinking more about it; the item should have been resolved in ZZZ. I believe the long delay for maintenance (swapping aircraft) led to the push to get the aircraft to ZZZ1. Upon arrival; after looking at the aft door; we noticed that the lower snap had been installed on the wrong side. I called maintenance control and we coordinated contract maintenance with ZZZ1 ground operations.

Narrative: We waited over 35 minutes for an aircraft swap due to a broken lavatory. Once we got a new aircraft; the cabin was very hot. We took several minutes to let the aircraft cool with the APU. My first flight with the FO. I had been off for two weeks (due to COVID); so I took some time to get all set up and start with solid Crew Briefings for FAs and FO. During pushback; FA called to say the banner on the aft door snap was broken. She told me that it was no big deal right now and I assumed I could look at it upon arrival into ZZZ1. The aircraft was terminating in ZZZ1. During the flight after thinking more about it; the item should have been resolved in ZZZ.
