[Mobile] Can’t edit shapes

I migrated my files because that was the only way to find out if I could edit them. It appears I can’t edit the shape that surrounds my text, though it still auto scales to frame it. I searched high and low for the option and could not find it. It’s either missing, or far enough away from intuitive to be an issue. I can’t return to the last version because you explicitly locked me into this version.
