IMSS enrollment with residency — finally got it to work!

Okay, so I finally got registered with IMSS after getting my residency here in Playa del Carmen. It was a bit of a maze, tbh. They tell you one thing, but the reality is slightly different. If you have temporary or permanent residency and are wondering about the steps, I can share what actually worked for me. Just trying to get my clinic assigned felt like a quest.
