I am plagued with endless problems with the lastpass app. For quite some time I have run into an issue where lastpass will not remember passwords that it generates, and usually I have to revert back to an old version to work around. Yesterday it disappeared from Firefox and I had to reinstall. Now, I see that copy/paste of my passwords is gone... which is a feature I use very frequently to login to apps outside my browser. I hate to say it, but I am looking at alternatives now, even after being a paying customer for years.
