I have been using Notesy and it has been working flawlessly for the longest time. My last sync seems to be on the 27th, and I believe at that time, I was on IOS 11. It says dropbox error. The only thing I've done was upgrade to 11 and I think I did it on that day, but don't remember. I've sent an Email to the developer, but on checking the domain, I don't think they will get the Email I sent which included some debugging info which I sent yesterday. Is there another app I can use? Its important as I have things I need to sync with dropbox so I can make corrections if I mistype. I suppose I could use google docs but don't think I can have folders within docs to keep things separated. Thanks for any ideas.
