KWGT must gain an access to the "Usage Information Access" (so called feature permission, at least on Huawei phones) phone information to provide accurate Traffic Stats. This is according to my research comparing to permissions other apps (e.g. GlassWire) use and these others provide correct data comparing to totally incorrect KWGT's, unfortunately. KWGT seems to be reading some kind of phone cache data which resets often and is short in today and even in yesterday's data, older data does not exist at all ... I hope this will be fixed soon.
