Expired Portuguese residence permit and flying through Amsterdam

Hello all,
Like many of you, my travel plans have been thrown out of order by COVID, and I'm afraid I'm going to run into some problems at the airport. I have tried to speak with multiple people at customs but unfortunately, they were of no help. Here is my situation:

       My Portuguese temporary residence visa expired on February 22, but I have an appointment for renewal in June, and I have a copy of the official email that acts as an extension to my permit until that time. I was set to fly back to the states this week out of Lisbon, but my flight was canceled and the only other one I could get was with an overnight in Amsterdam.

        I have flown many times in and out of Portugal with my expired permit, and the email was enough to get me through customs without a problem. Now I am worried that I will have some problems with customs at the airport in Amsterdam. The email works for Portuguese customs, but I have not had to use it with another country so far, and I cannot find any info about whether they would even accept it.

        People have said that if you have a Schengen visa and it expires, you can leave the area for a day and come back for the 90 days as a tourist without penalty. I did leave the Schengen area and returned on February 23rd, the day after my permit expired, but I am not sure if those rules apply to temporary residence permits as they do to visas. Again I have not been able to find any clear information.

       Has anyone had any experience with this sort of situation? Sorry for all the information, I tried to make it as clear as possible. Thank you!
