I’ve gotten to the point where I’m afraid to install your updates because I feel like it’s a 50/50 shot as to whether performance will degrade as a result. Sure enough, I was forced to install a new update, and I’m continuously running into problems I never saw before the upgrade. Please do better QA or stop forcing us to update to continue.
Your assumption that they do any QA is ungrounded. I’d assume the opposite.
