We are planning on performing maintenance on Notes sync this holiday weekend. We plan on starting the maintenance on Monday, September 7th at 2PM PDT, and we expect the service to be offline until Tuesday, September 8th at 8AM PDT.
You will still be able to create notes locally, however you will not be able to sync them up to our servers. There will be an exclamation point indicating that there is an issue with Sync, but that will be resolved once we have completed maintenance. Rest assured, all your data will be secure and preserved.
Everyone on the Documents Team appreciates your patience as we undergo this maintenance.
