When you hover over an enactment in the enchantment table it should show what main enactment which is guaranteed to be shown before actually enchanting an item but it has not been doing that on iOS preview 1.19.80.20 and 1.19.80.21

Same issue on Android.
Edit: Appears to only affect touch controls. I tried connecting a keyboard & mouse, and the enchantment appears when hovering over the slot with the cursor. Enabling text to speech for UI also makes the enchantment popup appear.
