TL:DR I bought the old gold membership and it expired, if I renew it do I get all of the same perks and benefits?
If your app shows the old plans you have an outdated app.
I don't know if it will actually let you purchase on the old app or not. Generally, if you let your membership expire, a new membership will be on the new plans and pricing.
