I am posting these new findings after doing some tests. The results are troubling and The Evernote team really needs to address this. When you have more than 250, everytime you will try to sync a new note it will give you the error and then it will look like it went away and it's now syncing BUT HERE'S THE CATCH! If you go and look on a different device, like your Ipad or the web client, The note itself will have been uploaded but it will be created in your default notebook , NOT in the notebook where you created it on your desktop. So what this is doing is breaking the symmetry you once had on all your devices. Now Notes will be at different places. NOW here's what's even scarier . If you make any changes in that note on that other device, it will sync and then move your note into the default folder on the desktop app. SO that means it is disorganizing your notes ! You will be looking for said note and it will have disappeared and moved to your default folder. What This means is that what once was this beautiful symmetry on all your devices is now all screwed up by the inconsistencies introduced by this 250 limit. Another thing that makes no sense what so ever is that Once a notebook is created you can not change it's sync options. So there is no easy way to manage tis 250 synced notebooks limit by toggling them on or offline. And since it does not warn you nor let you monitor how many notebooks you currently have, when you create a new one it defaults to synced notebook even if you are over your limit . It would make a lot more sense if once the limit reached it could only create local notebooks. At least it would prevent us from messing up all our notes by the previously described scenario. I dont know how no one at EN has missed this issue...
