Conflicting info about Puerto Rico Portal?

Excited to see the entry requirements have changed for vacinaated travelers starting 10/1. We are a party of 8 connecting through PR and on to Beef 10/22. Has anyone traveled recently? Do you have to do the PR portal if not leaving the airport? And when coming back home to enter the US do you have to do the PR portal or can you show your negative exit covid test at the airport? Thanks.

If you are staying in the airport, no portal required. I just did it on 8/26. Will do it again on Saturday and update if something has changed but I'm confident it hasn't changed.

You show your negative covid test at the Beef Island airport.

During your return to the US, after you clear immigration and customs you will be stopped by the National Guard before you can get on the elevator to the security area. You just show your connecting flight information and they allow you to pass without a portal approval.
