Unable To Enable Automations

[Donna]

For whatever reason, Trello is not allowing me to turn on my automations in any new boards that I have set up.

It keeps throwing the following notification:

I have exist the program and logged back in and still to no avail...

If the built-in automations aren't working for you, you could try using Power-Ups instead. I personally use Board Assistant (https://trello.com/power-ups/685016dd47b5654ae385bba6) for this kind of stuff.
It has some handy features like managing members in cards automatically or adding comments when things change. They actually just added a feature to mirror board structures to other boards, which might be useful since you're setting up new ones. The developers are pretty active and usually open to suggestions if you need other specific automations added.

It will only allow me to enable one automation with one library...

This is so disruptive to say the least - not sure how much time we have lost as a business this year on the functions being tappered/updated and not being restored properly after works have been conduct in the background.
