I'm facing a problem while you un-reconcile and cancel a paid invoice >> becose the Balance of a journal like Bank or Cash does not move. I tested with a paid invoice (lets say with +$100) to journal Bank (with a balance of $1500). Cancel all the journal entries (that works fine) but then you will see that the balance does not move -$100 to $1400.
I also tested this issue right now on a Odoo.com database. Do you have the same like me?
The problem that I'm facing is the fact, that the un-reconciliation of invoice - payments is not being reflected in the Bank or Cash balance.
