Thanks for taking the time to share your feedback! You’re right as it stands you only have the option to load all comments which can be tricky when you have hundreds of comments on the same task. We already have threads on this topic, I’ve listed them just below and would recommend reading through them, adding your vote and add a comment if you wish too!
I would like to see an option that removes the “See more” link and just shows the full comment. The “see more” link is way to subtle and people don’t see it, so they are missing important info about tasks longer than a few lines.
