Twitter is not working

[somansu chauhan]

Twitter is not opening/working in my Lumia 520. There is no update/install and review buttons in store either. What the hell is going on.
Is twitter not available for wp anymore?

Twitter is still available. You might try doing a soft-reset. That is, power off and power on the device. 9 times out of 10 that will fix an issue like this, because it's usually a memory corruption issue. It can happen to any device with any OS.
