Earlier this month, BlackBerry, after announcing the BBM for Windows Phone in private beta, had opened registration for the closed beta test, with the list closing in less than 24 hours with quick entries.
The instant messenger app from BlackBerry can now be downloaded by closed beta testers, and since the app is in a beta stage BlackBerry has also noted some limitations or errors that might occur in the BBM app for Windows Phone.
As per a BlackBerry email sent to testers, the following are known issues to the company.
Invites and acceptances don't send when Windows Phone goes out of WiFi coverage
A few newer emoticons are not rendering properly (i.e brrrr, and flex and @-@)
Windows Phone shows as available for BBM Voice call although feature is not supported (seen on Android and iOS, not BlackBerry 10)
Error popup appears when using "Find Friends" and the "OK" button is selected
Suggested Contacts tab only shows users already using BBM, but lists them as potential contacts when BBM is initially launched.
The BlackBerry Messenger app for Windows Phone has been long-awaited since the company had launched the BBM app on Android and iOS in October last year.
