A couple of months ago I bought a Dasaita Vivid 11. When I was on holidays, Spotify app stopped working. I switched to Amazon Music as I was planning to switch services anyway. After a while, the search function of the Amazon Music app stopped working (always showed a "loading" spinner). I uninstalled and reinstalled the app, and now I can't login because it says it has no internet connection. It's strange because it lets me input my username and password, but fails with the internet connection error after entering the two factor authentication code, despite it being correct.
If I open chrome browser, Internet doesn't work either despite WiFi being connected. It happens both on my phone hotspot and on my garage WiFi. If I clear Chrome cache, it starts working for like 5 minutes, and then it stops again.
Despite this, Google Maps seems to work well and updates traffic, and I can download apps from google play with no issues.
I also have issues with other apps: Sygic won't even start (it shows an error). HereWeGo worked at first, but recently it refuses to get the GPS position and gets stuck wherever I started the car.
I decided to the hell with everything and tried just using android auto with Zlink, but as soon as I start moving the car, a message that says "return to home soon" appears, and the radio returns to the launcher. It doesn't really close android auto because music keeps playing, but it makes it totally useless. If I open it again it works for a few seconds before showing the message and closing again.
I'm absolutely tired of fiddling with this thing. I have no idea what the hell is happening... apps start working and after a few weeks everything starts breaking down for no apparent reason.
Is my radio faulty? I can't understand what's happening. It makes absolutely no sense.
