Thanks for posting in the community! I'm sorry for the trouble you've been experiencing. In order to test if it is actually a bug, I'd like to take a few basic troubleshooting steps to eliminate other potential causes. Could you try opening your document in a private or incognito window? Could you also try connecting to a different network? Sometimes account performance issues can be related to internet security/speed or browser issues.
If these don't resolve the issue, please submit a ticket here with the following:
- The URL to your document. If this happens in multiple documents, please let me know.
- The version of Chrome you are using
