Same here. Doesnt matter if i try accesing the router from my pc browser or phone browser, the phone app also gives "Unknown error occured" when i try to log in. I always get that screen, i reboot the router then it works, but only for a couple of hours maybe one day max, then the problem comes back.. Getting sick of having to reboot the router everytime i want to log in to see or change anything.. I also did factory reset after the update.. In the upper right corner at the exclamation mark where it says" Some Router features are not running" sometimes i get "Telemetry" sometimes "---". Also the system log spams "Time went backwards" continously every couple of seconds. I did set the right timezone tho. Beside the geofilter, the smartboost tab also doesnt show anything, it gives the tutorial popup to "To get started, press + blablabla".. How am i supossed to know that the router does what its supposed to do if the settings dont even show untill i reboot then? xD
