Players won't be able to stack their PlayStation Plus subscription anymore, ahead of a major revamp to the service

sportskeeda.com:

PlayStation Plus users were able to game the system ahead of the PS+ revamp, but it seems to have been disabled now. People were subscribing to both PS Now and PS+, and using it to get a longer subscription of the higher tier when the revamp comes through.

When the new service launches, users who have a subscription to both will receive an upgrade to the highest tier of PlayStation Plus, for the duration of their longest subscription. However, that option seems to have been disabled since people were taking advantage of it.

PlayStation owners who planned on stocking up on years of PlayStation Plus just to cheat the system are finding that they aren’t able to do so now. It was brought up on social media, with one user asking Customer Support about the problem.

The resulting answer was that the ability to stack PS+ subscriptions has been temporarily disabled until the changes come through in June 2022. People who didn't have it before were picking up PS Now, just to try and get several years of the highest tier of PS+ in the future. While it was a smart idea to try and game the system, it appears that enough people have done it to cause it to be stopped entirely.

It basically allows people to potentially have years of the highest tier for significantly less money. As of right now, users can’t stack either membership if they have an active membership.

This has since been confirmed by support emails coming from Sony.

This is also affecting users who are about to run out of their subscriptions to PlayStation Plus as well. There have been reports of users simply trying to simply add time before they run out, but aren’t able to, likely because of this change in Sony’s policy.

Sony has yet to make an official statement about this
