We just moved into a rental home after selling our home and waiting for our next home. It has 3 toilets.
Someone was in the shower and the toilets started bubbling, all 3 toilets. The shower was not backing up. I tried flushing one of the toilets and it started to fill with water. After about 20 minutes we plunged all the toilets and the water went down.
I understand it is a rental but we were very lucky to get this rental for a short term lease and if there is an easy fix (my husband is a repair man) he would do it himself.
I don't know if this makes a difference but the day before we moved in there was a storm and the roof above a half bath was damaged. The roof was fixed that day, but a piece of drywall around the vent is being fixed monday.
Ive read some threads on the issue, but I have never heard anyone say all the toilets bubbled when one specific shower is turned on. The toliets are not even close to each other. The house is 2700 sq ft on one floor. No neighbors are having issues. We are in a HOA that maintains the water service (sewer). The house is one a hill, level lot but on a hill. It has a small pool and spa that run all the time (like water spilling over from the hot tub to the pool in a loop. I don't care if this feature is on and didn't know if turning it off would help.
Any advice would be appreciated.

This is a classic symptom of a restriction/blockage of the main sewer line downstream of the toilets. No way to know for sure without scoping with a camera and/or running a mainline sewer cable.

It is the HOA's responsibility to clear this up. If you don't feel comfortable reporting it because you are subletting, have the leaseholder report it. How will you feel reporting it if there is a backup which floods the entire unit?
