It’s only normal that software developers would patch up security holes in their apps. Unfortunately, there are rare times when such fixes actually break existing third-party features. That seems to be the case here when Google introduced a patch to the beta version of Chrome for Android which has effectively blocked LastPass from applying its autofill feature on web page forms.
Neither can really be blamed in this unfortunate situation and Google can hardly be expected to reverse that critical security fix just for the sake of LastPass. The good news is that there is still some time left before Chrome beta becomes the next stable release and LastPass developers are trying to work with Google to see if a win-win solution can be found or if the patch can be reverted. In the meantime, LastPass users on Chrome should switch to the stable version 36 of the browser or some other Android web browser that supports plugins.
