Why is QGIS not refreshing after updating a connected database?

It is a MS Access Database which I connected to QGIS using ODBC. The database contains coordinates of some vessels and they are already visible in QGIS but it is only refreshing when I disconnect and then reconnect the db connection. I am looking for a solution the past few days but I am not possible to find any.

I use QGIS to access Filemaker databases via ODBC (also to map vessel data). I find that it will refresh with new data when QGIS is forced to re-draw, by either zooming or panning the map.

I recently detailed how the QGIS-ODBC-Filemaker connection is made here:
