Re: Error downloading and installing games.

Got the same with Mirrors Edge Catalyst.

I see in the log file lots of messages like this when the retry is attempted:

   114	[2020-12-12T16:07:09.359Z]	  9288	WARN    	(?)	[Qt] [CRITICAL] file[https://pc.ea.com/static/js/vendor-main-253ae210.5eadd1ac.chunk.js] Uncaught (in promise) Error: Download - message failed to send with error: Error: Failed to find the download session

One thing to note is that I did shut down my computer while the initial download was ongoing, with intention to continue later after rebooting. This might be a contributing factor.

EDIT: Indeed, after canceling the download and restarting it, download all 20 gigabytes again (what a wasted bandwidth...) without interrupting the process, it completed fine. Could be just a coincidence, but a possibly important data point to consider.
