Unfortunately I can't help you with the answer to your question, but I can tell you that it is a brilliant ecosystem full of genuinely supportive and amazing people and that's why I'm still here after 2.5 years and I feel like I have a better friendship happening with more people on here than my IRL friends, so whatever you do, stick with it and as many people told me when I first stumbled upon Hive back then and had to spend hours researching and reading to learn not only about Hive, but also Blockchain/crypto and the rest, have fun and don't freak yourself out (like I was doing trying to understand it all at once...) and I'm sure that your questions will be answered.
RE: Why does it seem that I always have to go through the login process twice using HiveSigner?
