Previews of Drafts in text messages is Gone

Question

Hello. My phone (Google Pixel) restarted today after an update, and now I cannot see all of my drafts I have pre-written in my text messages for different people.
To be extra clear since I could not find an answer anyway I worded it on Google -- I used to make myself notes for a text message that I would not send, and I would always see the preview of the unsent message in my text window for all of my texts. 
I have tried to research a way to undo the last update, however, I do not see a way to undo it, as well as specifically undo messages update.
Does anyone else have this problem? Do you know of a fix? 
This is detrimental to me being organized because I usually have 20 work conversations (99% of the time, all new numbers, unsaved, so can't decipher who & what's who) going, and it takes way too much time to reopen every conversation & reread my messages. I very much RELY on text draft preview to keep my life and business simple...
Thank you thank you everyone!

I found kind of a workaround for my workflow.  There is now a "Mark as Unread" feature. 
In list of messages, press and hold message(s) to select > 3 dots in upper right corner > Mark as Unread
It doesn't solve the preview issue, and it's a pain to do the extra step. But to find my drafts, I can at least mark them as unread for now.
