I had written INNOVV to ask them if they would fix the INNOVV app to allow for multi-selecting files for downloading. They wrote back and told me...
""in fact the files can be mutil-selected and download, would you please check your APP to be the latest one or not? Please serach in the google or apple store for the new innovv app, it should be INNOVV, not INNOVV K2 NOW, k2, k3, k5 are with one APP""
I downloaded the newest version of the INNOVV app and found that it does have multi-select options.
Plus, I noticed that the download speed was way faster than when I used the INNOVV K2 app.
I've attached a couple screenshots to help you get to the multi-select page. It took a minute to figure it out so I thought this might save you guys/girls some time.
I have the K2, so your experience may vary. But I'm pleased with the behavior of the new INNOVV app that I installed today.
