| | Re: No twitter alert Bold 9900
I had the same problem before with many accounts. actually, it happens sometimes when you receive a mention or direct message but no alert shows on device.
This problem happens caused by Twitter server itself and has nothing to do with your BB device.
In such case i used to open application and refresh it manually to find any new mention.
Twitter services differ between devices and browsers, e.g: it may be working probably on IPhone but not on BB, it may work fine on Firefox but not on Google Chrome.
