I'd suggest checking manga forums or dedicated Bleach fan sites. They often have detailed breakdowns and recommendations on where to pick up after a specific part. Sometimes, the author or official sources might provide cues as well.
Honestly, I don't know when the TYBW manga starts. But you could search manga databases or ask in manga enthusiast communities to get the details you need.
The TYBW arc's starting chapter isn't a straightforward answer. It could be different based on the manga version and region. I suggest looking at dedicated manga websites or asking fellow manga enthusiasts for the exact chapter.
It means that the visual part of the anime, especially the sakuga which is like the cool and detailed animation work, is great. However, the story fails to deliver. Maybe it has a boring or unoriginal plot. You know, like some animes where the art style and the animation of things like magic spells or action moves are super impressive, but when it comes to what's actually happening in the story, it just doesn't hold your interest.
It can be normal. Many fans like to engage with multiple aspects of a fandom simultaneously. Watching 'Bleach' and reading its fanfiction can be a way to satisfy different cravings for the story. For example, the fanfiction might explore character relationships in more depth or present alternate plotlines that can be really interesting to compare with the original series.
