Okay, I knew that many keyboards could be moved, but I never actually found a use case for the feature. I don't know why it hadn't dawn on me before.
I just sent you a DM testing out if the input box would flow into new lines (it does) and if I can move my keyboard at the same time as using speech-to-text. (Yes, you can). (And yes, I'm horrible at texting and so I tend to use speech to text.)
Anyway, it's not a fix obviously, but it's a better work around than what I was using before. I feel silly for not thinking of it before, so thank you for reminding me! 💯
