Can I remove Modern Comments and revert back?

Question

My Word (on Microsoft 365) has updated to Modern Comments. I have a number of problems with the useability of these comments, based on the way I have used them in the past (for context, I am an educator and primarily use them when marking student assignments).

• The main issue is that autotext is no longer supported in a comment. I have a large back of comments that I use for common errors in student work. Some of these comments are up to a paragraph, or contain URLs to instructions for certain things. It's incredibly helpful to be able to insert these quickly and will increase my marking time substantially if I can't use them.
• Comments are slow to open. If I open a comment using a keyboard shortcut (on a Windows computer) and start typing, the first one or two letters often gets inserted into the main text
• They don't use the same autocorrect tools as the main text. My typing has evolved to use those features. Two capital letters at the start of a comment don't get corrected, and simple typos don't get corrected
• There are more steps to use them than before. I don't share my documents, so being able to edit comments and post when they're finalised is not particularly useful for me, as no one else is looking at them until I send the document. However, I can't click out of it to finish, I have to click or ctrl+Enter to post. I also can't just click INTO it to edit, I have to click on more buttons.
• It doesn't make sense to only be allowed to edit one comment at a time, particularly if the idea is to not post them until you're ready to share with others. Sometimes in the course of writing one comment, I want to comment on something else first and then come back to the previous comment. You're forced to finish one first, to the standard you're happy for others to see, defeating the purpose of not having to post until it's finished. Why not allow multiple to be in draft?
• If I forget to post and try to type a new comment, it pulls me back to my previous comment and starts typing, making me lose my spot where I wanted the next comment
• It has added an extra space to the side of the document, which wouldn't be an issue except that making any formatting changes under tracked change, which I often also do when marking assignments, goes into the ORIGINAL pane where comments use to be, widening the document even further (extra space for formatting, then another extra space for comments). My computer screen isn't large enough to cope with the extra width.
• Once I post a comment, it's still selected. There have been a number of times I've posted a comment then tried to ctrl+F something in the document, but it won't respond to my ctrl+F. Not something that is necessarily a huge issue but it is annoying and I can't see the purpose for keeping a comment selected when it's posted and non-responsive.

I'd either like for this issues to be fixed with Modern Comments, or for an option to be provided to allow us to go back to the previous version of Comments.
