I have just installed this new webapp and it's great. I normally access my OpenOffice-365 email account via a Morph Browser bookmark and everything works as it should. Yesterday I tried the OpenOffice-365 Webapp and logged in to my account. It was really snappy and I like it. I tried it on my M10 tablet and my Nexus 4 and it performed well on both devices.
The only snag was a freeze which occurred when I opened the Junk Email folder and selected a message for deletion. This issue was repeatable on both my devices.
