So after the release of Dragonflight, I’ve gotten problems daily with world server is down, getting stuck in the loading screen, or transfer aborted: instance not found. I have tried playing with no addons, didn’t help. Reset the interface. Run the advance troubleshoot and even deleted and redownloaded the game. I still get the problems.
Unfortunately, random DC’s and so on seem to be part and parcel of the Dragonflight experience for some people, coupled with lag, choppy frames and stuttering, and - if you’re on a Mac - the inability to play the game at all for nearly a week now.
There’s not much that can be done from this side to help, but if you can post a bit more detail about your computer specs and so on there might be something that jumps out ?
