Glad you had an easy go of it. It messed a lot of things up for me and I had to ultimately cobble together a bunch of scripts that would find the mistakes so I could go in and manually correct each one (with like three extra clicks than necessary for each operation because Bitwarden's UI is trash). I think people who only used really basic LastPass features may not have had those problems. But I had LastPass Family with sharing and folders and it was a massive mess because the LastPass export was buggy and then incomplete. And Bitwarden is not able to iterating on fixing imports so you're stuck manually correcting import errors and duplicates. Not to mention that editing and updating in Bitwarden is a real pain in the ass because bulk operations are missing. I was really shocked at how shitty Bitwarden's database tools are when I actually had to try and use them.
That happened to me only because I imported the file twice or three times, thinking records would be overwritten when they completely matched. Oh, and because it also imported deleted (but not flush/emptied out) entries, which in hindsight I found it to be a good practise. Aside from that, importing was straightforward and categorizing the many uncategorized entries a breeze compared to LastPass.
I have over 300 passwords, multiple cards. Multiple notes. All synced flawlessly.
