Please be aware there is a temporary problem with SkyDrive sync in MobileNoter SE and MobileNoter SE HD for Android. The issue has occurred because SkyDrive connection protocol was changed by SkyDrive developers; we've reacted rapidly and have already published the hotfixes for MobileNoter SE/SE HD on Google Play. But, unfortunately, those our customers, who installed the app from Amazon Market, are still facing inability of SkyDrive synchronization, especially Kindle Fire owners. Updates on Amazon Market appear a little bit later than on Google Play, so you need to wait for about 1-2 weeks.
We apologize for this issue and confirm that it has temporary nature.
