The other comment is great, as a plan B this app is what I use for automating just about anything on android.

It takes a little while to get used to the block programming, but it's fun and can do lots of stuff. The free version should work fine on an alternate android-based OS, but I haven't checked myself.
Edit: used to use. I haven't actually been on stock android for a while, and I haven't used the app in a while either.
I made the jump to signal, and those that refused to come with got relegated to SMS.
But it's not always that easy. Sorry that you have to deal with that BS.
