Unfortunately it's one of the most bug-ridden and unreliable pieces of software I've ever used. I encounter issues with it on a daily basis, but the burden of switching and a lack of superior options keeps me locked in.
I've more or less switched to apple keychain/passwords at this point. I need a solution for linux, and have been thinking about some kind of simple 1-way sync issue that dumps stuff from keychain into some other tool for use on linux.
In terms of TOTP I just use googleauth and oathtool.
I was a paying customer for 15 years and migrated away with the last price increases due to "AI-powered functionalities" and the new features making the product worse on top of already being salty over when they stopped the one-time licenses in favor of subscription.
It won't ask me for my secret key, which I have an can provide immediately, no, it won't allow me to authenticate myself with the phone, because our enterprise vault logs off quickly, I must however do a some absurdly obscure dance because FY, that's why.
