There’s another similar thread here: 🚨 [MAJOR ALARM] "Google AI Pro" Paid Users being Locked out for 167 HOURS (7 Days)! This is UNACCEPTABLE - #25 by partarstu
I’ve also commented that after removing some extensions for quota monitoring and auto-accept yesterday I finally got normal Claude quotas again.
UPDATE: After fully using 5-hourly quota with Claude only twice within 24 hours, I can see again the lockout for the whole week. It means that the mentioned by me extensions are not the root cause and Google further keeps very low quotas on Claude models for PRO users.
