Since yesterday, when adding a job via the schedule, it is no longer letting me add to a specific group within the board once board is selected. The Group option isn’t appearing at all? Is this a bug or a permanent change? Also when I click on the three dots we can no longer see a little 1 appearing if there is note, it says start conversation and then I go in and can see the note.
Hey Chloe! Welcome to the monday Community! 
When you say “schedule tool,” are you referring to the “Work Schedule” page in the Administration settings? Could you please share a screenshot to capture what you’re referring to? I want to make sure we’re on the same page so I can take a closer look at this with you.
I am referring to when you are in the the My Work Calendar view, and click into add a job - it no longer shows Groups within the boards.
Also it doesnt have a little (1) when I have added notes, it just says ‘Start Conversation’ despite the fact that there are notes in there.
Did you manage to get this resolved? We seem to be having the same issue as well. We can still see the groups in the bottom of the dashboards but when you click on the task itself the group no longer shows. We checked all of the settings, and it seems like this function has just disappeared.
