Hi there,
First off, thanks for choosing Guitartricks as your place to learn guitar!
If you've been taking lessons for a little while, and you know how to play some chords, you might want to start with Guitar Fundamentals 2 here: https://www.guitartricks.com/course.php?input=fundamentals2
If you want more info on where to start, check out this blog post on how to get started with Full Access: https://www.guitartricks.com/blog/How-to-Get-Started-with-Full-Access
In regards to your plateau, this is pretty normal. It's always fun to jump-start your guitar learning by tackling songs, which we have over 1000 officially licensed song lessons! Check those out here: https://www.guitartricks.com/songs.php
Learning songs is my favorite way to pick up on new techniques and hopefully it helps you as well.
