Just in case someone from Google actually reads this and all the threads where people complain, even with Pro, about hitting Quota limits and/or OAuth failures, here is RCA:

(Extension runtime starts.)
(Init-order bug: extension tries to use LS client before it’s ready → breaks auth/user-status wiring.)
(LS comes up after the extension already failed.)
(Auth token never gets set in LS → treated as not logged in.)
(User/plan fetch fails due to missing token; “singleflight” just dedupes concurrent refreshes.)
(LS is running, but unauthenticated.)
How it should be (expected)

I just got hit with a 4 day wait as a paid pro user as well. I am also seeing that I am not logged in despite the UI saying that I am. Here is the results of my output

So, a little different situation but it appears to be the same bug.
Bugs can exist. The real issue is that google is not being transparent with the issue, not giving an estimated time to fix it, and we are blind to this.
2026-01-30 02:39:14.470 [info] W0130 02:39:14.469730 9904 client.go:137] failed to set auth token

So why does the UI shows we are logged in while we are not? This is one of those bugs that are hard to believe they are in good faith.
exactly, normally it wouldn’t take them this long to fix it, could be intentional to limit the amount of tokens consumed on foreign agents (talking about anthropic), if not they have to compensate the users with a paid subscription, at least an additional 2 weeks of pro. I hope I am wrong.
The Claude quota limit issue is not due to auth error. The latest update 1.16.5 solved the issue mentioned by OP, but still the quota limit issue still remains.
Here is the latest log at the time of writing:

Anyway, the quota/auth issue has been resolved with this update. In my case at least.
And I feel like they introduced some throttling for Claude models, but I noticed it in opencode, not in Antigravity, so I must investigate further and verify.
Well I see the changelog, but I don’t have the update available in the IDE, I assume I am in a different batch, will get it later. But do you have a link where it can be download from maybe so that I can install it?
Glad to know it’s fixed on your side, but I’ve just re-installed 1.16.5, logged out-in many times and I am still kicked out until Feb, 09. I am a Pro user:
yes, I’m also stucked till 9 february… but in my case i reached cooldown before I got 1.16 version… so I will wait for reset, and the will see what happens
