I found the board sync problem, working on it now. I was able to reproduce it by adding a pane with a calendar pane open, and it cleared all of the panes in the board (but only the beta ones). I’ll try to get a fix out soon.
I think the problem with missing items is from an old bug where moving items between documents marked them as moved but didn’t correctly move them to the new document. The old sync system was very forgiving and only used that as a hint, but I forgot about that and make the new system ignore all moved items. I investigated @Jorge’s document and found that to be the problem. So the items should still be there in the database, it’s just deciding not to show them. I’m still trying to figure out how best to fix it, but I will try to solve it asap.
As I was making the new sync system I found that document ordering was not really working right previously, and a lot of documents just didn’t have any order, so they might reorder randomly after signing out and back in. So I just removed the concept of ordering completely and made them alphabetical just to get it working faster. Do you think manual ordering is an important feature? If so I can add it back in, but more correctly.
I think trying to migrate to a new account would cause more trouble than it’s worth. I’m trying to fix all of the old problems as part of this new sync system, so old data should not cause any issues. And once this is all stabilized I’ll add features to fully delete documents and to clear out deleted items. I think that should be a better solution than starting over.
For the mobile update issue, are you using the beta version (under About Legend in settings)? That version number is the latest stable mobile version. If so, is that iOS or Android? I’ve tested on my Android and it’s updating correctly and I’m not sure what the issue would be…
