I like using this app to organize my to-do items for my company which subscribes to office 365. However, since the latest update my app constantly says "unable to sync" even though it appears to be working when I check in the browser on my desktop. Even uninstalling and reinstalling the app doesn't fix it. I can't trust the app with my vital work if I'm getting sync errors like this because I cannot lose anything. Please fix this and I will update to 4 or 5 stars.
