I know the issue is that the extension manager looks for updates. But why does it have to look for updates all the time, ie. every day? Why not weekly? Perhaps the method to check if there are updates could be simplified, first request a general token to see if there are any updates at all, before checking individually, if that's how it works.
Not sure if this is the place to ask or post this, but hey, maybe someone has a workaround for me?
