So I went to modify my new staff (thanks, battle admins:), and I guess I haven’t done that for awhile, because drag and drop the mods is not a thing either my iPad or my iPhone understands. At all. >.<

I tried everything I could think of, from tissue paper gentle to screen-imperiling insistent, even tried clicking the mod then the empty slot, then tried it the other way round, but nothing worked.

Is there something I’m missing? Have I finally lost my mind and what I’m doing wrong is obvious to everyone who isn’t me? Enquiring minds, and all that.

Thanks. Oh, fwiw, both are recent models, with the latest iOS installed.

Haven't done drag & drop, but I had an idea of where that be located, tested works fine on computer but not my phone (android) so I assume the drag and drop is not touch screen compatible thing (at least that what it looks like)

anyways how I modified my weapons so far is to go to: inventory click on the mod > click "Modify Weapon" > find weapon and click slot i want mod to go, should say something like "Put your X here!" > press ok on the warning pop up > now your weapon is modified > repeat for next/other mods

A bit more tedious but this should work for you at least

OmG, I didn't even know that was an option! Silly me! this is soooo much more convenient than the drag and drop in a massive armory!
