There are 2 main reasons for a blank screen being displayed in either the Paragon or Electron versions of the Symphony Desktop Application.
In Electron versions prior to 1.53 - 3.4.1 and Paragon versions prior to 1.52, a caching issue may occur intermittently. This problem typically presents an error message similar to the following displayed in the Developer console (Figure 1):
Figure 1 Error Message
Refresh your Symphony client to resolve this blank screen issue. If the caching issue persists, refer to the Knowledge Article found here on how to clear your cache.
If the issue persists after you have refreshed and/or cleared your cache, please contact the Symphony Support team at email@example.com and inform them that you are experiencing issues with a blank screen.
In versions prior to 1.54.2 - 3.7.3, if the Symphony Desktop Application was impacted by network connectivity issues on a computer, it would fail silently and produce a blank screen without any information.
Instead of this blank screen, users now see the following error message (Figure 2):

If the automatic reconnect does not resolve the issue, refresh your client.
If the issue persists after you have refreshed, please contact the Symphony Support team at firstname.lastname@example.org and inform them that you are experiencing issues with a blank screen.
