Preflight Checklist

- This is a single bug report (please file separate reports for different bugs)
- I am using the latest version of Claude Code
What's Wrong?
I upgraded from Max 5x ($100) to Max 20x ($200) on Thursday, July 16, 2026 (prorated charge confirmed, plan shows Max 20x in settings). Since the upgrade, my weekly usage limits deplete dramatically faster than they did on Max 5x — not 20x more capacity, but effectively less than my previous plan.
What Should Happen?
After upgrading to Max 20x, weekly usage limits should immediately reflect the 20x tier — i.e. roughly 4x the capacity of my previous Max 5x plan, per the Help Center ("you receive your full weekly allowance each cycle").
Concretely: on Max 5x, ~4-5 Opus messages consumed 1% of the weekly Opus limit and my allowance lasted 6-7 days of normal work. On Max 20x, the same workload should consume proportionally less (roughly 16-20 messages per 1%) and comfortably last the full week. Instead, consumption is at ~2 messages per 1% — worse than the cheaper plan I upgraded from.
Expected fix: recalculate the weekly limit counter to the Max 20x tier for accounts that upgraded mid-cycle, and restore/credit the usage lost since the July 16 upgrade.
Error Messages/Logs
Claude AI usage limit reached. Your limit will reset at [date shown in app]. No error in CLI — weekly usage percentage jumps ~1% per 2 Opus messages despite Max 20x plan.
Steps to Reproduce
- Subscribe to Max 5x plan (baseline: ~4-5 Opus messages = 1% of weekly Opus limit)
- Upgrade to Max 20x mid-cycle (July 16, 2026 — prorated charge confirmed, settings show Max 20x)
- Continue identical daily workload (Opus 4.8 primary, Sonnet for subtasks)
- Observe weekly limit depleting at ~2 Opus messages per 1% — worse than Max 5x
- Weekly cap reached in 3 days vs 6-7 days previously on the cheaper plan

- Suspected cause: weekly limit counter/tier not recalculated after mid-cycle upgrade
