This just happened to my 14 Pro case, slightly over a year old. Out of nowhere, the sides just became loose (this happened on both sides). I take good care of my phone and in the past year, I didn’t remove the case often because this is my only one. A quick google search showed that the same thing happened to others as well. I paid the casetify premium only because I expected it to last as long as this phone would (ie. at least 3 years).
