My experience with the app was fairly good for about five years, until now, when they've made having this extension and the app on your phone at the same time a premium feature.

Honestly, it is not the best. The UI is always clunky. If and when I allowed it to do overlays to autofill it's always a significant problem and puts in the wrong thing after preventing me from doing what I'm trying to with a very slow popup that messes with everything else.

Changing passwords can be a problem. If you happen to lose your phone with Microsoft or Google's Authenticators on it (or just delete and re-download the app) you'll discover you're in very real trouble if you were using them for 2FA because they generally aren't locked to your account but your phone (at least, this was the case in 2019, things could have changed). With that, despite having the password, one working 2FA code that I could provide consistently, and every bit of information about my account and its usage it still took me weeks to regain access to my password because of how slow customer support is to free users - that last part I at least understand. I will note that their policy says that their people will never ask for your password, but mine did way back then. I spent a long time stewing over the possibility of some random lastpass employee selling my passwords online, and they could have in the time it took for them to tell me 2fa was finally disabled. I'll still never know about that for sure. It's also somewhat funny to me that Lastpass, the people that protect my passwords, are the only people to ever ask me to send a random employee on the other end of a text chat my master password in cleartext. Or ask me for it at all.

This application for handling the most precious and private things you have comes with seven trackers on Android. That is significantly more than its competitors. That and effectively making having your passwords everywhere you go a premium feature was a good enough reason to leave it behind. I will not be coming back.
