That is true of all software. :-D
I am using CS6 of Illustrator and PS but stopped upgrading the MacOS at OSX.12.
PS is buggy now and I’ve switched to Affinity Photo now.
Affinity is a direct reaction to the highway robbery of Adobe.
Quark has upped its game as well to compete with Indesign.
Still only playing with Designer as I work faster in Illustrator. ( started back in 1992)
All in all, Affinity will replace Adobe in the future. It just needs the time to integrate new features.
Like Adobe did throughout the 90’s and very early 00’s.
Adobe stopped major feature rich updates and lost revenue so they switched to “leasing” and forced people to upgrade/pay.
