BlackBerry on Saturday hit pause on the rollout of iPhone and Android apps for its popular BlackBerry Messenger mobile social messaging service after an unreleased version of the Android app was posted online.
That version saw 1.1 million active users in the first 8 hours, the company said, but the unofficial version "caused issues," which the company continued to address throughout the day.
The company did not specify what the issues were.

BlackBerry says it is slashing 4,500 positions in a last-ditch move to recharge the troubled company.
The Canadian company said it would eliminate that many jobs in a bid to cut expenses, a move that comes two days after The Wall Street Journal reported an expected 40% workforce reduction at the device maker.
BlackBerry has failed to invigorate its business despite unveiling a new smartphone line and software in January. The tailspin has prompted company officials to explore strategic options, including a sale.
Troubled BlackBerry said the layoffs will help slash operating expenses by about 50% by the end of the first quarter of 2015.
"It could make them seem a more attractive investment -- to buy or invest or go private. I think all of those are on the table at this point," says IDC analyst Ramon Llamas.


Customers who have already downloaded BBM for iPhone will be able to continue to use it.
"As soon as we are able, we will begin a staggered country roll-out of BBM for Android and continue the roll-out of BBM for iPhone," the company said in a release.
The unreleased version of the Android app will be disabled, the company said. Those interested in the official Android app can visit the BBM.com site to register for updates on availability or follow @BBM on Twitter.

The issues have not impacted BBM service for BlackBerry, the company said.
In May, the struggling firm announced that it would be rolling out BBM, perhaps the company's most popular service, to other mobile platforms. It had been exclusive to BlackBerry smartphones. The service features BBM Chat for instant messaging with other users. Additionally, each user has a unique PIN, so you don't have to give out your phone number to use the service - a privacy feature.
