What's Wrong?

The weekly usage reset date shown in Settings > Usage shifts arbitrarily forward when the weekly limit is exhausted, and subsequent reset intervals do not consistently equal 7 days.

Platform: Claude.ai (iOS app and web)
Plan: Pro

Steps to reproduce:

1. Use Claude normally during the week and note the reset date shown in Settings > Usage.
2. Exhaust the weekly usage limit.
3. Return to Settings > Usage and observe the reset date.

Expected behavior:
The reset date should remain stable throughout the week. The interval between resets should consistently equal 7 days.

Actual behavior:

• Before the limit was reached, the reset date was shown as Tuesday.
• After the limit was exhausted, the reset date shifted forward by 3 days to Friday, without any actual reset occurring and without usage being credited back.
• After waiting until Friday and the limit reset as shown, the next reset date is now displayed as Tuesday again — only 4 days later, not 7.

The reset date appears to shift arbitrarily forward when the limit is hit, and subsequent reset intervals do not consistently equal 7 days. This makes it impossible to plan usage reliably.

Related issues:
This behavior matches the pattern described in #51222, where the reset time changed without an actual reset occurring. Filing separately as it reproduces on a different account and the specific symptom (3-day forward shift at exhaustion, followed by a sub-7-day interval) has not been documented in that thread.

What Should Happen?

The reset date should remain stable. Resets should occur every 7 days.

Error Messages/Logs

. Note the reset date in Settings > Usage (shown as Tuesday). 2. Exhaust the weekly limit. 3. Return to Settings > Usage and observe the new reset date (shifted to Friday, +3 days). 4. Wait for Friday reset, then check again (now shows Tuesday, only 4 days later).

Steps to Reproduce

1. Note the reset date in Settings > Usage (shown as Tuesday). 2. Exhaust the weekly limit. 3. Return to Settings > Usage — reset date has shifted to Friday (+3 days) without any actual reset. 4. Wait for Friday reset, then check again — next reset shown as Tuesday, only 4 days later.
