Description of problem, include YAML if issue is related to notifications:

Folder / Sub-folder links into the media-browser are not working.
E.g. in the browser {externalURL}/media-browser/browser/app%2Cmedia-source%3A%2F%2Funifiprotect will open the Media Sources -> Unifi Protect Folder.
Using this URL as a clickAction in a Notification will open the Browser.

Using homeassistant://navigate as suggested in the wiki full URL homeassistant://navigate/media-browser/browser/app%2Cmedia-source%3A%2F%2Funifiprotect is showing an error
Invalid media source URI

Companion App Logs:
Can't see anything related in the logs. Please advise in case needed

Looks like the app opens this as {external}/media-browser/browser/app,media-source://unifiprotect?external_auth=1 (viewed using Chrome remote debugging), so I guess Android and/or the app are decoding too much.

Did you try to double encode the URL?

[jpelgrom]

No, I'm following your example?

No worries!
I've tried using a double encoded URI: homeassistant://navigate/media-browser%2Fbrowser%2Fapp%252Cmedia-source%253A%252F%252Funifiprotect
but same error.
