UniDBGrid does not refresh when underlying FireDAC data changes

[Alex S]

I have a TUniDBGrid linked to TDataSource linked to TFDQuery linked to TFDConnection using Postgress (PG) driver with default options.

I have two browser instances open with the TUniDBGrid. When I make changes in the TUniDBGrid in one browser instance, it goes all the way through to the Posgress DB. I confirmed this on the server using PGAdmin.

However clicking on the TUniDBGrid refresh icon in the second browser instance does not refresh the changes. Only a whole browser refresh (CTRL-F5), loads the changes. 
What also works is to add a dedicated button that closes and then opens the TFDQuery.

I suspect some caching in the TFDQuery or TFDConnection? Any advice what to change to the TUniDBGrid refresh icon works correctly?
