Usage on Account A is reflected in Account B's "Account & Usage" panel and vice versa. Three captures taken minutes apart show:</p>
| Account A (Max) | Account B (Pro)
-- | -- | --
Session (5hr) | 68% | 67% → 68%
Weekly (7 day) | 94% | 94%

Regardess of current stats towards your usage, both accounts share the attributed usage towards limits.</p><!--EndFragment-->

What Should Happen?
Expected behavior:
Each account's usage should be tracked independently against its own plan's limits. Activity in window #1 should not affect Account B's allowance at all.
Impact:
Pro plan exhausts at the same rate as the Max plan it's running alongside, even when only the Max account is being used.
Makes running parallel work across separate accounts (e.g. personal + work) impossible without effectively double-billing the smaller plan.
Combined with the prefix re-billing on session start (which I observed at ~10% per fresh session), the usage burns down faster than expected.
Error Messages/Logs
0 error messagesSteps to Reproduce
Repro steps:
Sign into Account A in VS Code window #1 (Claude Code extension).
Sign into Account B in a separate VS Code window #2 (different extension session, different account).
Run any work in window #1 — observe usage tick up.
Open the "Account & Usage" panel in window #2 — usage on Account B has moved by the same percentage.
Reverse the direction — same result.
