Currently there is no way to view how many daily downloads you got on your add on for Android.
90% of my downloads come from Android users so it is very evident to me that the download count shown on my analytics is very clearly only for computer users. I haven’t been able to find any information regarding this or anyone else experiencing this issue I would assume it’s not really important for most people but since Firefox is the only extension supporting browser for mobile users this is how all of the mobile users who want to install my extension install it and I have no way to see any analytics for their downloads.
