• Tech debt (refactoring, code cleanup, dependency upgrades, etc)
• Build/deploy pipeline (DevOps)
• Other

Objective

iOS extension is not loading.

This was an unintentional feature of our appearance tweaks in #1556. We used the ThemeManager to call colors for appearance adjustments before we had a ResourceDictionary loaded.
