Themes not working

The new Themes feature in Niagara Launcher are currently non-functional on both the free and paid versions. Tapping on it causes the launcher to hang briefly and then return to the Niagara settings homepage or Home Screen without applying any changes.

Steps to Reproduce:

1. Open Niagara Launcher

2. Go to Niagara Settings > Themes

3. App hangs for a second

4. It either:

Sends me back to the Niagara settings homepage

Or

(if reopened after app restart) redirects me to the coloros launcher even if Niagara is default

What I tried:

• Tried on latest versions of both free & Pro versions

• Cleared cache & data

• Restarted both app & device

Note: it works on my second phone Redmi S2 though
