Google assistant won't open, even when I have the beta versions of both Google and play services.

[AC Question]

I succesfully installed Google Assistant trough the beta versions of the google app, and the google play service.
Google Assistant is correctly installed becaus I have the settings of it in the google app.
To activate Google Assisant, you need to press, and hold the home button, but when I do that, it opens Google now.
How can I fix this?
I'm using TCL 560 5056U.
Android version-6.0.1

I've been through this and managed to get it work by clearing the cache and data of the google & play services apps.
