Version 0.3.2-4
I am using Oauth

'Error retrieving tweets Server returned 400:'
No this only happens once or twice a day. Usually when I try to refresh by pressing the circular arrows bottom left; speech bubble to left; circular arrows bottom left.
I am not sure what the api rate limit actually is but I was playing around with the settings and may have moved away from the most efficient way of setting it up. I have:
Time line - 1 sec
Mention - 5 secs
DM - 30
Public - 90

Followers: selected Friends and refresh and got the error 'Error retrieving tweets Server returned 400:' four times.

The + tab brings up a menu at the bottom +20 +50... but this does not load more Tweets.
hmm, it's supposed to, again helps to know if basic auth or oauth
No does not work, no not even get the timer spinning in the top bar.

"Sometimes when I launch the app there are only one or two tweets or none but when I check on twitter.com there are dozens."
Sometimes the twitter api doesn't seem to return the full list of tweets, I think it's their side rather than mine, as it happens occasionally.
Occurs more with retweets if that is helpful information.

Your pint should have been delivered to you.
Many thanks
