How do I know which projects I am on?
Seeing your own projects is part of the baseline every account keeps, so no permission grant is needed for it. Two records answer the question differently though: the resource count on a project says who is attached to it, while the capacity plan says who is expected to spend hours on it this month.
Attachment and allocation are different facts, and confusing them is the most common source of a planning argument.
Being attached to a project means your name is on it. Being allocated means somebody has planned hours for you against it, on specific days.
A person can be attached to six projects and allocated to two. Both records are accurate. Only one of them describes the month ahead.
The capacity plan is where the second answer lives. A grid of people against days, with hours in each cell and a monthly total per person, showing bands from under-allocated through to over-allocated.
Leave and holidays are subtracted before those bands are read, which is what stops a plan quietly assuming somebody is available on a day the office is closed.
Your own time logging is the third view, and the one that records what actually happened. Hours logged per project, by week or month, against the expected hours for the period.
Planned and logged disagreeing is not an error. It is usually the most useful thing on the page, and the gap is worth reading before anybody is asked about it.
A project you support occasionally may never appear on any allocation. Unplanned work still gets logged against the project, which is why a time log sometimes names projects the plan never mentioned.
Check the allocation grid before agreeing to new work rather than counting project names. Six projects at two hours each is a different week from two projects at twenty.

Can I see other people's allocations?
The capacity grid is a planning surface and follows the resource allocation permissions. Seeing your own projects sits in the baseline every account holds.
Why does my project list differ from my planned hours?
Because attachment and allocation are separate records. Being on a project does not mean hours were planned against it this month.
Does the plan account for leave?
Yes. Leave and holidays are marked on the grid and taken out before the allocation bands are read.
