@twister ,
I have a thought you might go this way (which is what I do on all my deep-linked apps navigating to a record).
App OnStart
If(
!IsBlank(Param("AppID")),
Set(varID,Value(Param("AppID"))),
Navigate(DetailScreen, Cover)
)
Item of the Form you are going to
LookUp(
SPListName,
ID=varID
)
then if you are navigating also from a Gallery - OnSelect
Set(varID,ThisItem.ID);
Navigate(DetailScreen,Cover)
