Static Tab and Chat Tab Order Is Not Persisting in Microsoft Teams

manifest file:

"staticTabs": [ { "entityId": "schedule", "name": "Schedule", "contentUrl": "...", "websiteUrl": "...", "scopes": ["personal"] }, { "entityId": "conversations", "scopes": ["personal"] } ]

the Schedule tab is intentionally place before conversations: it initially appears correctly, but after navigating away from the app and returning, Teams places Chat/Conversations before Shcedule. I'm using schema version 1.12.

The tabs are configured in the specified order in the manifest file, and the expected tab order is displayed correctly when the app is initially opened.

However, when I navigate to the Chat section, the tab order changes and does not persist as defined in the manifest file.
