How to Activate and Use "Card Dependencies by Screenful"?

unknown

I installed the "Card Dependencies by Screenful" power-up to all of my Workspaces & Boards. I can see that it is enabled as a power-up.

How do I make it work with Cards?

I watched the animated GIF on the Screenful site but none of the things shown in the GIF appear as options for me on my Boards & Cards.

For example (from the Screenful instructions site):

After enabling this Power-Up from the Power-Up directory, you can start setting dependencies between cards by clicking Card Dependencies at the right side menu of a card. An input window opens that allows you to select the type of dependency you want to set:

The above does not work. There is not a Card Dependencies at the right side menu of on the card

Thanks!

I am running the Free Trello product in Chrome on a Macbook.

I've got some guesses:

Possibility 1
Try going to the Enabed tab in Powerups, then click the Settings button under Card Dependencies. Then "Authorize Account".
To catch the possibility that you missed/skipped Screenful's authorize step that happens immediately after you Add their powerup.
If I'm completely off-base, then you will not see an "Authorize Account" option, only "Remove personal settings". In which case this answer will not be applicable.

Possibility 2
Login and open the board in incognito mode, or on a different browser just in case.
This is to catch the possibility that you have an extension or adblock that is not allowing the Dependencies button to show up.

Possibility 3
are you accessing this on your phone? as powerups don't work on the phone

Hope one of those apply.
