AdvoSync is for advocates in Indian courts. If something on the board or in the app does not look right, this page and the address at the foot of it are where to start.
A case is matched to a cause list either by its CNR or by the name you appear under. Add the CNR to the case if you have it — that is the only exact match. Otherwise check that the spellings under "Name on cause lists" include the way the list prints your name.
That listing was found by your name, not by a CNR. Two advocates can share a name and lists are typed by hand, so AdvoSync will not claim it is yours. Confirm it and it will be treated as yours from then on.

AdvoSync has no reader of its own; it hands the file to whatever app you already use. If a document is marked as not on this device, the file was removed or the app was restored from a backup that did not include it.
