We have just received word the Twitter for BlackBerry in the BlackBerry Beta Zone has been updated to v220.127.116.11. This build includes several bug fixes, some of which directly address several of the concerns noted by beta testers in our discussion forums! For a full list of fixed and known issues, please check out the updated KIL (coming this afternoon).
Also if you are having an issue with Push @mention here is a workaround that should help you.
Development has come back to us with a workaround for the push @mentions issue that several users have been experiencing. This will be changed in the beta refresh build due out early-March.
Please follow the steps below (they are very straightforward)
1. Enter the options screen and turn OFF the “Notify on replies and mentions” and save the setting
2. Re-enter the options screen and re-enable the “Notify on replies and mentions” and save the setting
Push @mentions should begin working moving forward.
