Yes. This is often overlooked. But the number 1 complaint I have always heard on any platform I've managed is "I can't log in".
Number one complaint I’ve heard is that new accounts appear blank and can’t follow people. Nostr account creation and propagation is bugged. Need DHT badly.
DHT maxxing
It's still hard to make your first follow on ditto. When you create a new user and try to follow someone it often doesnt. But if you go to another client, do it, and come back, it works. That said, overall, ditto is still by far my favourite client. I am #ditto only now.
