This could be a double definition.

'message online' is the first definition.

'call from branch?' is the second definition.
'tweet' can be an answer for 'call' (I've seen this before). I am not certain of the 'from branch?' bit.

'and' is the link.

Can you help me to learn more?

(Other definitions for tweet that I've seen before include "Birdsong" , "little message" , "Communicate" , "Note of a small bird" , "online comment" .)

I've seen this clue in The Telegraph and The Sun.
