Streaming updates/ Websockets errors on update to 0.34

Was the streaming updates button removed from the UI in 0.34? I ask because I’m no longer seeing it on mine since the upgrade. It appears that I am still seeing updates reflected in sensors and I don’t see any specific errors, but I am getting a number of websocket errors from the new websocket api:

The sidebar menu entry has been removed, it is no longer possible to disable streaming updates. When an error occurs a toast will show up in the bottom left of the screen.

Those errors are, uhm, interesting. Haven’t seen them before.

Today I learned when it’s time to be concerned. :laughing:

I put in an issue for this. Release docs didn’t mention the missing toggle, perhaps that should be added. Came as a bit of a surprise to me and a few others.

I’m also losing connection in the UI and I added my notes to another user having the same problem.

I’m having the same problem as in the last issue. Frontend: Connection lost. Reconnecting. I don’t see any errors however in the log-file. If there is anything I can do to help, let me know.

You should comment on the Issue by clicking on the link. That way whomever is working the problem can be aware of how many users are affected without having to check the forums.

Done. I’ve added my comment.
