I recently updated to 0.103.0 running on a Ubuntu 18.04 server VM. Was making changes and after a reboot found the web UI stuck on “loading data”. Removed recent config changes, custom components, etc with no avail. Built a new Ubuntu VM, installed hassio, and started applying my configurations. Stopped for a while and came back to the same “loading data” on the new web ui.
Found someone else having the same issue and they suggested it was the Todoist configuration. I removed my Todoist info from Configuration.yaml, rebooted, and it worked. Did the same thing to the original VM and it also fixed the problem. Any ideas on why Todoist would mess up 0.103.0?
