I've been experiencing the following problems using Evernote 5.4.1 (App store version) after upgrading to Mac OS Mavericks. These problems are identical on both my iMac and Macbook Pro. Problems: General slowdown when accessing notes and notebooks. Newly added Microsoft Office docs not viewing inline (previously added docs are fine). When annotating PDFs the annotations are not showing until the note is closed and reopened.Is anyone else experiencing these problems? Are they known bugs? Evernote - will these be fixed soon.
