All three of my devices updated fine.
One quirk, after I logon after the update (happened on all three)
An upload dialog box appears.
UPDATE: It happens after every logon, I just close the box and continue on.

Update 7.0.0500 applied on F5-221. Only observed issue was numerous messages "Failed to retrieve data" on restart. Everything appears to be working, though.

A re-boot a few minutes later displays no such errors.

f2-221 and f5-221 updated without any real issues. Good job.

One minor thingy: on my f5-221 the AppCenter icon kept showing 2 updates available, but when opening the app center there were none.
After a reboot no more messages.
