Guessing this is a bug. Mine was working fine yesterday. Exported files fine. Today I had some kind of issue connecting to my file on the server, so I ran a bunch of updates to make sure it was all the latest. DB Manager was falling on it's face and I was able to get that resolved. Now I can't create accountants copy. Contacted support and they just send me this link, which I already saw, which doesn't have an actual answer. In practice, the workaround isn't much better than just making a backup and sending it to the accountant. Seems ridiculous that we still have basic functionality issues at this point.
