I recently upgaded PiAware from 3.3 to 3.6.2 via tracking home page control panel. The upgrade went OK, but I quickly discovered that I no longer have any Altitude or Speed data. Both columns are blank and when you hover a mouse over a target, both fields show N/A. After playing around with things for a while, I discovered that Skyview was working properly in Firefox V. 61.0.2 and the problem is with Chrome (V. 68.0.3440.106). It still works on Chrome on my Android phone.
