The release of Android Wear 2.0 is being delayed once again by Google. The tech giant has explained that it has a software bug that needs to be squashed before the new smartwatch OS could be widely rolled out to everyone.

Google’s Android Wear 2.0 update was first announced almost a year ago back at the 2016 I/O developers conference. The software was supposed to arrive in the fall of the same year but was pushed back to early 2017.

Although newly released smartwatches like LG’s Watch Style and Watch Sport came pre-installed with the updated OS, owners of older devices continue to be left with the older version of the software. Unfortunately, it looks like users of the dated software would have to keep on waiting for Android Wear 2.0.

In a recent statement provided to 9To5Google, Google said that the update will arrive for everyone, but the company has discovered a bug during its final stages of testing. “We have started rolling out the Android Wear 2.0 update to Fossil Q Founder, Casio Smart Outdoor Watch WSD-F10 and Tag Heuer Connected,” the company said. “For other devices, the update is currently being delayed due to a bug found in final testing. We will push the update to the remaining devices as soon as the issue is resolved.”

To be fair, Google has never really given an exact release date for the software. When LG’s brand new pair of Android Wear 2.0 watches were released back in February, all Google said was that the update will be rolled out to everyone else “in the coming weeks,” as pointed out by Engadget.

There’s really no way of telling when Google will finally release Android Wear 2.0 for everyone. It could take days, weeks or even over a month if the company can’t iron things out quickly.
