The Facebook app works both on the iPhone and the iPad
Just hours after Facebook's release of its long-awaited iPad app, users have started reporting minor bugs.
Some said it should have been tested better to ensure it
worked properly with peripherals developed for the iPad, such as the
iPad dock.Facebook admitted that there were some bugs, but said that it was not unusual for new products.
The app comes out 18 months after the launch of the first Apple tablet.
Available for free at the Apple app store, the program is actually an upgrade of the existing iPhone app, tweaked to fill the larger iPad screen.
The interface for the application lets users "pinch" the screen to zoom in and out, as well as swipe to flip through photos that fill the entire display, as with a real photo album.
A Facebook spokesperson told BBC News that all products were always "vigorously" tested before launch.
"However, as with all new technology products, occasionally unexpected bugs will surface once people start using products on a mass scale."
The company added that it was "following up on feedback".
'Repeated delays' iPad owners have been pondering over the lengthy wait for a proper Facebook app ever since the tablet was first launched, back in 2010.
Some users have reported bugs - like the "Send" button not appearing when the iPad is on a dock
But the company did not go into any detail about why users had been forced to wait so long.
"We're releasing it now because it's done," said Bret Taylor, the firm's chief technology officer.
It was reported in September that Jeff Verkoeyen, the application's lead developer, wrote in his blog about the app's repeated delays despite it being almost finished several months ago.
Bugs found But shortly after the app's release, users have started complaining of a number of bugs.
Michael Clawson wrote on Twitter that he was not able to see his pages when clicking on left panel icons.
Another user, journalist Mark Coyle said that the app came "complete with a glaring bug".
"I have an Apple dock/keyboard, and if you put the iPad on the dock then try to comment on a post, the 'Send' button doesn't appear," he said.
"Take it off the dock - it appears. Poor testing by FB."

According to Facebook, of the 350 million people who access the social network on their mobile devices every month, about half do so through a web browser and half use applications built on their phone or tablet operating system.
