Summary

Bug report: The app fails to render hashtags with a minimum length of 2 after modifying the setting in the system console.

Environment Information

• Device Name: iPhone 15 Pro
• OS Version: iOS 17.5
• Mattermost App Version: 2.16.0
• Mattermost Server Version: 9.8.0

Steps to reproduce

1. Open the Mattermost system console.
2. Navigate to the database settings.
3. Change the minimum hashtag length to 2.
4. Attempt to use a hashtag with a length of 2 in the app.

Expected behavior

The app should correctly render hashtags with a length of 2 after changing the minimum hashtag length setting.

Observed behavior (that appears unintentional)

The app does not render hashtags with a length of 2. It still only supports hashtags with a length of 3 or more.

Possible fixes

Potential issue in the codebase where the hashtag length validation still enforces a minimum length of 3. Consider checking the validation logic for hashtags in the app's code.
