I find journalling in the day pages clunky for a lot of reasons. For one, it makes it really hard to revisit specific thoughts unless you can remember the dates that you made them.
The solution I found is having a separate 'Journal' page that I use for all entries. I use a shortcut that appends the date and location to the end of that page and I start writing underneath. All the entries are on the same page, so I can just scroll back in time to revisit past entries.
