Have you tried BitWarden? I recently switched after using lp for the last 6 years. Couldn't be happier. Things just work with BW. It's simple and convenient. Also being free doesn't hurt.
There was a period circa 2014-2015 that LastPass was pretty glitchy on Firefox in MacOS, but for quite a while I've had no problems at all with it - it just works. Even my non-technical wife has no issues with it, and sharing secure passwords is a breeze.
