In the latest Messages for Android Beta, scheduled send is broken due to a date validation bug. It won’t let you schedule messages after today’s date number in any month. So, for instance, today’s date is 29 November, 2023; it won’t allow any messages to be scheduled in December unless they’re scheduled on the 29th, 30th, or 31st. Also, it won’t allow any messages to be scheduled in 2024, for what I assume are similar reasons.
Reverting to the latest stable version fixes it and allows messages to be scheduled for any future date.
Just wanted to report that I’m also having the same issue. I’ve tried clearing my cache and force stopping the app but I still have the issue.
Have you tried leaving the beta?
I haven’t.
It was a huge pain, but I was finally able to do it by leaving the beta, uninstalling updates, clearing cache, restarting phone, and then updating the app. I finally got the non-beta version, and scheduled messages works.
Same issue on v20231128
