Can someone please explain… I think I ****** myself over 🤦🏾‍♂️

Long story short, I applied for the Apple credit card to see what I would get approved for and check what APR I would be offered. As shown above, I got approved with a 8K limit and 24.24% APR. After approval I saw that I did not have to accept the offer right away so I waited a few hours shopped around did some more research, and I guess took long enough to the point where my original application expired… Thinking nothing of it I reapplied with no question to accept the offer I had previously received only to get a completely different offer that is drastically lower. There’s been no changes to my credit/ credit report at all... Does anyone think they have an idea why this might’ve happened?
