I am unable to use my downloaded stickers while messaging
I have not been able to use my downloaded stickers while messaging for quite a while. This initially happened with my iPhone 13 Pro Max. I thought I would be able to start using them when I received my iPhone 5 Pro Max - NOTHING. If I hit the "+" to the left of the input area, it will allow me to select stickers, it shows sticker selection banner, and then immediately goes back to where I input messages. Various upgrades have occurred, numerous resets have happened and I still have not been able to access my stickers. When speaking with Apple support, they could not help me. I would like a resolution after going on almost 2 years with this problem.
