The alignment option seems to have disappeared from the formatting bar for buttons on my page. How do I align the button? Thanks!
Excellent question! In WordPress 5.4, the button block was updated to support multiple buttons. So, the default behavior when you insert the block is now to focus on the first button.
To change the alignment, navigate outside the individual button — but still inside the area designated for it — and you should see the alignment options again.
Hope this helps!
