Hard to convince colleagues to use it

We chose ClickUp after we tested monday.com - which was quite expensive as we had to pay for every user, even people who maybe have to set a comment less than once a month. Unfortunately, the ClickUp UI isn't as intuitive as monday.com, so it's pretty hard for us to convince our colleagues to get started using it. ClickUp has massive issues with its Information Architecture, and UX - with Spaces Folders, List, Docs, and somehow everything can be nested everywhere. For Example, I share spaces with many users from a service company - all users have been "Guests." ClickUp let me do that, but it's not possible for guests to access Docs directly in a "Space". The ClickUp support instructed me that I have to add docs into a "Folder" to be able to share them. I had to change the whole structure because when I asked if they would fix the "bug", the answer was it works as intended! Luckily not many of my Team members have started using ClickUp, so are able to switch the platform a third time (or just go back to simple google spreadsheets)
