there is some confusion… deeplink is something else than deephost…
deephost is an extension developer, who does not support his extensions and a lot of them are buggy, therefore using extensions from deephost are not recommended
and the deeplink extension which we are talking about in this thread is from Sunny and he is unfortunately suspended in this community… for questions about the extension, please ask on github or open an issue there GitHub - vknow360/DeepLink: Add deep link support to apps (For MIT AI2 and its distros)
