Hi!
Internally some team members have reported the same issues.
Our most recent release, 8.39.1, has many improvements around downloads.
One of which is the ability to turn off “background downloads”.
Not to get too into the weeds but we think there may be a bug with the API we use for downloads in iOS.
So if you go to Settings > Downloads > Turn off “Use Background Downloads”.
Then start a download and keep your app open, you may have a better experience.
This is just a workaround we put in to make downloads usable in these cases.
