I’m really sorry that you’re still having this problem. I can only imagine how frustrating this has been. It seems like quite a recent thing with a number of other users. Many of the things others have suggested before me have worked to settle this sort of issue in the past. After reading through those suggestions as well I’m all out of ideas. This issue you’re having has been brought up to Raz though by a couple staff including myself. I don’t know when he’ll have more time to look into it and perhaps sort it out but at least know you’re not getting ignore.
The only other thing I can suggest is to make sure you’re not using VPNs
