I contacted mdc support for your issue n.3:
- Fix the issue that two users cannot introduce a manual session on the same time/hour, if user nro.1 worked yesterday from 08am to 11am, user nro.2 cannot do it, and in real cases there are two people (or more) working for a task in the same time/day, so this has to be fixed. example: error message trying to add a session on the same time that my partner
They propose to “open a column for each of the people who will need to track time in the board. You can always sum those time tracking columns if that is important using a formula column”. This works as a workaround in our use case, expecially setting visibility for each user.
I can just suggest @Julia-monday.com and mdc team to to make an option: “duplicate this time tracking column for each member and sum them in a formula colum”.
