I am having the same issue which has only started today. I’ve tried the steps outlined above and it hasnt resolved the issue for me. I have also looked into the logs and this message is repeated regularly:
NETWORK:error (6) sending player state
The logs also contain:
[7:48:44] Problem 429 logging analytics: Could not acquire access token due to throttling
[7:48:44] Error changing user profile: Could not acquire access token due to throttling
