Nathan - thanks. I checked it out and everything seems to be working fine.
I think it was just a matter of time before our running of back end updates to all QB Online accounts was completed. So by the time I tested it out, your account was already update with the latest and greatest.
I was able to edit a note and restore it for a test customer, and it looks like every customer has the latest sync now from QBO.
One tip (side note): something I noticed when testing out your notes - on your customer list, I suggest lowering the initial list to 10 customers at a time. The screen loads much faster that way, as loading with 100 each time will slow you down. If you temporarily need to see more than 10, you can use the + sign at the bottom to expand. The thinking here is that most of the time you are using the customer list to do a search anyway, rather than a scroll, so it is much faster to do a search and return and format 10 results rather than 100. You'll see quite the difference.
