It’s undoing work that was complete, its changing forms or pages completely unrelatated to what you’re working on. You ask it to undo a change from 15min ago, and it starts undoing things from 3 days ago, then tells you that was all in the past 15min. For developing a complex system, it has recently become a disaster. It wasn’t like this a week ago. Am I going crazy or is this what others are experiencing?
You are not! Same here.. totally for complex and big system this has become a joke… too slow and doing nothing… and not entering anymore in antigravity anymore … Google had a problem with theGemini outage 10 days ago, and they are saying they fixed it.. but that is obviously a lie… it just doesnt work anymore for big project and i will def cancel my package in google this month … try for big project opencode with deep seek… it is monster how googd it is and problem solving… i have 160k lines of code and deepseek is eating it without a problem best of all it cost 5 usd and google cost 90!?! im using pro in antigravity now only for desing 
lol and my friend report he uses ai studio..hes saying its a killer over there ?! idk, but antygravity ide with gemini pro …
