[BUG] Max 20x upgrade not reflected in weekly limits — depleting at Max 5x rate or worse (upgraded July 16, 2026) #79773

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

  1. Subscribe to Max 5x plan (baseline: ~4-5 Opus messages = 1% of weekly Opus limit)
  2. Upgrade to Max 20x mid-cycle (July 16, 2026 — prorated charge confirmed, settings show Max 20x)
  3. Continue identical daily workload (Opus 4.8 primary, Sonnet for subtasks)
  4. Observe weekly limit depleting at ~2 Opus messages per 1% — worse than Max 5x
  5. Weekly cap reached in 3 days vs 6-7 days previously on the cheaper plan
