When I started using BunPro daily, I was also doing daily listening practice, and I started reading native stuff pretty regularly. Without the extra exposure to and reinforcement of the grammar that I was learning, I think BunPro wouldn’t have been as effective and sustainable for me. So what worked better for me was not to study grammar in a vacuum. 
You can consider participating in one of the book clubs. Or the picture book challenge, if you think manga and books are still too much right now.
Unfortunately not every resource clicks with everyone, but I hope you’ll find something that works for you!
