Frustrated and sad with new 24+

I splurged and bought a new s24+ to replace my S9 and I am so frustrated. So many of my apps don't work, can't log onto Samsung pass, or wallet, so can't use saved passwords, the yahoo app can't connect to Internet so even resetting passwords one at a time on each site individually can't be done because I can't get into my mail.

I want to cry. This was so much money and it's awful so far. Had to put sim back in my old phone. Can't even open my work app on the new phone because no saved passwords and I have hundreds of apps and sites with passwords.

What am I missing? I feel like I must be doing something wrong on the setup although I'm not usually tech challenged.

I did the wireless transfer, should I have done wired?

Any advice?
