I am our Salesforce admin and I've started to use Lightning to get familiar with the interface. I was downloading our weekly Data Export files and noticed an odd behavior. When I click on an individual Zip file to download, the Salesforce interface goes to a white screen (can still see navigation); it then prompts me to download the file, but when it completes the download I have to hit the "Back" button to get back to the Data Export screen to download the next file. I tried this in both MS Edge and IE 11 and the same behavior occurs in either browser. I'm not sure if this is a bug that Salesforce will want to try to replicate?
I've done some simple work with visualforce and displaying it with lightning (to download files) and have seen the same behavior. I suspect it's because the LEX executes an action but returns nothing (eg. action is the click but the result is the file is downloaded from server).
I don't think it's a bug as much as it is some incompatibility that the Salesforce team would need to work out with the action and behavior on the page. I suspect the page is also the same page shown in classic which is why i call it incompatibility. The feature is not impacted but the experience of clicking multiple files for download is.
Anyone else have thoughts about this?
