We have a custom activity "Activities Required" which is present as a Sub-grid on an entity
There is a 1:N relationship between the entity and custom activity.
The 1:N relationship is a part of the left hand side navigation on the form designer.
However, we do not see the associated grid button on the sub-grid. Also records created using the + button does not show up in the sub-grid.
These records however do show up on the Associated view of the entity record. Any ideas? [This works with custom entity but not for custom activity]
