Bug in the last update requires re-install
I made a mistake while publishing the last extension update on Friday, 14th Feb 2017.
While moving from the old Dropbox API to the new one, I forgot to update settings in my Dropbox developer account. This meant that the extension suddenly stopped working for some users.
I’m sorry for this blunder!
I have resolved the issue from the back-end. However, for those already affected, the only solution, at the moment, is to remove and reinstall the extension.
It will start working normally again.
This is required only if your Todo.txt extension stopped working after the last update. If the extension in your browser is already working normally, you do not need to re-install. It has already been patched.
App Updates 
Hi, When will you have a version of the app that does NOT require another service like DropBox?
Hi Nigel
I’m currently working on an update that will also work with Google Drive, as an alternative to Dropbox.
I would like to support a local file based option, but Google’s Chrome API doesn’t allow that functionality for extensions. So, it’ll be a while before I can get it to work without a cloud based storage service.
Cheers!
