The Mini is "mini" for a reason, and as you use it you'll see other parts of iPadOS 15 is not optimized for it (just wait until you try to split screens or some other functions). I ended up returning mine for the multiple "quirks" of the Mini 6, but I do think it could be a good device for some use cases--just wasn't smooth at "enough" things for me to be worth the price premium.
I do hope it works out. The smushed icons ended up being just one of many things that, together, made me less likely to reach for it, which is a shame because I love the form factor.
