Do rings of protection stack?

[FabulousFizban]

If a pc is wearing two +1 rings of protection, do they get a +2 to AC?

[Contrast]

Additionally, a creature can’t attune to more than one copy of an item. For example, a creature can’t attune to more than one ring of protection at a time.

No, they can't.

No, they can't.

Though items with extremely similar qualities but different names do apparently stack, IIRC.

Consider, a Ring of Protection, a Blessing of Protection and a Cloak of Protection, all give +1 to AC and Saves, all should stack by the RAW.

You also cant attune both.
