This is a very frustrating issue. Ever since the November 2020 AMA that said apartment pools are ineligible, reviewers trying to follow clarifications rejected them. The AMA was quietly removed from the Help menu, and (much later) this clarification was made here and then added there:
What I would do personally is resubmit any apartment pool that was rejected with a note in the supporting that includes the new stance. Possibly
Please note there has been an update to the policy on swimming pools, and apartment pools are no longer ineligible: Swimming Pools
For the other type of Wayspots, I would point out to the reviewer to check the tool tip under Appropriate to see that “Private property” refers to SFPRP and/or link to that clarification here: Private Residences, Farmland & K-12
Make sure to be matter-of-fact about it in your statement. This is the only way I know to get the word out to increase reviewer awareness.
As to “used my last appeal”, you get two appeals, each on a 20 day timer before you can use it again. If you have the nominations available, I resubmit before appealing anyway. If you have a specific nomination that you would like advice on resubmitting, feel free to post it here.
