Next time, do your homework before splurging your money on expensive tech.
Whenever I buy pretty much ANYTHING that is over, say 100 USD or so, I read all available reviews, watch every YouTube video there is about it, and whenever possible I go and touch/handle/try the actual item in person before buying it ( all of this is very possible for pretty much any kind of Apple hardware... unless you are the kind of person that orders their newest tech on prerelease so you can have it on day 1 of release).
Try it next time, it will for sure save you from wasting money (god knows how much money it has saved me in all these years). If you had done so, you would have realized before buying the differences in the display tech between the 12.9 and the 11, how the iPad Air refresh rate doesn't match that of an iPhone 14 pro, etc....
EVENMORE: If you would have done your homework you would know that in the next 2-3 months, Apple will release an 11 inch iPad Pro that will potentially have an even better display than the current 12.9, so it will give you the form factor you want with the display quality of your current 12.9, possible making you regret having had bought the current 12.9 so near to its hardware refresh...
Bro, do your homework....Just my 002
