This is affecting me too as I have to use Linux at work..
I use both the mac/android version of Evernote and the web interface. I noticed that editing a note on the web interface cause the note to lose its formatting, list indentation in particular. The only solution is to revert notes and re-edit them and use the web interface as "read-only". This is making Evernote unusable for me as I have to use the web interface at work since I have a Linux workstation.
