Not to mention it is slow as molasses(on the cloud at-least) and the UI is unwieldy with way too many clicks required for the simplest of actions.

I am sorely tempted to build a frontend so that I can avoid wasting so much time on it. Just a better frontend not yet another project management tool that will not be bought by management.

I don't understand the slowness at all, even if their backend and architecture is Fubar to fix at this point without massive work, they could have handled it in UX with non blocking loading states, backgrounding actions which were slow etc?
