So: I've got a PebbleTime and:
- connected without problems
- notifications (sms, mail, call, android...)works
- timeline of course doesn't work
- no apps which needs companion doesn't work
- in INFO tab there is no apps!
- Running firmware is v3.5.2
- Latest firmware v3.6
...button for upgrade is active. Actually, My Pebble has newest firmware as it is available

edit: All messages are occurring twice, but no problem for that
