Large amount of storage used on watchOS

**iOS device model, version and app version**

Model Name: Apple Watch Ultra 2
Software Version: 11.6.1
App version: 2025.7.2

**Home Assistant Core Version**
2025.8

**Describe the bug**

The HA app on my watch is using 2.13GB of "Documents & Data" storage (while the iOS app uses only 244MB).

**To Reproduce**

Unclear, but all I use the HA app on my watch for is a complication that shows a temperature entity, which I tap on to activate some Quick Actions.

**Expected behavior**

Similar storage consumption to the iOS app.
