Major problem with the new version 3.0.6 (using Iphone 8 on IOS 12). My initial issue was with my screen periodically dimming while running OpenVPN. The phone was behaving like it would when it starts to overheat. Just discovered the cause of the dimming....the OpenVPN app is periodically bursting massive amounts of upstream data! This is with no apps running besides OpenVPN. Just rebooted phone, launched OpenVPN and watched as it pumped out 143 MB over a 4 minute period. Between 8 and 12 this morning the stats were showing 2GB down (not impossible since I was browsing alot of twitter), but 12GB Up! Watching the data graph in the OpenVPN app, you can see the burst of upstream data followed by my screen dimming. This app is overheating my wifi chip!
This is a major problem....gonna be some pissed people inadvertently burning thru their data plan.
