I'm on iOS too, and this makes chromatic drafts unplayable because drag-and-drop is disabled in the iOS client. The same is true for the Android client.
Also, disabling alt styles in the iOS MTG settings does not work - the setting flips back immediately.
Disabling alt art styles in the Android settings does not flip back, but just does not affect anything.
And selecting the "preferred" style for a card does not work at either platform (at least in Chromatic Cube) - no effect at all.

This is ridiculous.

Also, happened again in a draft because the draft server timed out and I had to recreate my deck….

DAC, playing on IOS so I am unable to drag and drop. Only the tap option appears for handheld when deck building.

This just happened to me as well in the Chromatic Draft with Raffine’s Tower and Zagoth Trimoe.

I am also getting blank headings in the settings menu.

Yeah I can't drag and drop cards on my phone. Does mobile have that?

Over here https://feedback.wizards.com/forums/918667-mtg-arena-bugs-product-suggestions/suggestions/48480350-cant-play-triomes-in-chromatic-cube it was suggested that drag & dropping it into the deck area will apply the base card style. Have you tried that?

I drafted two tri-lands that I don't own or own the card style which is stopping me from adding it to my deck during construction, probably until I buy the styles which I don't want. I can't drag the card as I'm on mobile. This is a pain as I need the fixing lol.

Kind regards,

Kieran.
