I can equip and attune to it, but I cannot seem to get DnD Beyond to roll an attack with it.  Can roll attacks with a common quarterstaff, but not the staff of striking.

 I just equipped one on a character and it showed up in Actions | Attacks as a rollable attack. The one thing is that you have to manually roll for the charge-based damage.

If yours isn't, provide the link to your character sheet so someone can take a look.

🛐 effing 💩!!!

That’s new. For years now, any “Magic Staff” has not displayed attacks because they hadn’t added any Actions to magic items, and since a “staff” is separate from a “Weapon” in the books, DDB hadn’t coded them to wack anything. (Yes, RAW, every “staff” can be used as a Quarterstaff, but that wasn’t supported before. For ever around here we have had to homebrew a “Copy_of_[Staff]” and switch the magic item type from “staff” to “weapon” and add the “Quarterstaff” weapon type as a workaround.

I wonder if that’s a result of them having to create “subtypes” for wondrous items to accommodate the newest releases? Or did they start adding actions to magic items as part of the update?!?

 This inquiring mind wants to know!!

 Paid subscriber, website. I just checked on the app too, it's there.

 I think they just made Staff count as a quarterstaff weapon. I don't see Actions yet for item homebrew, and things like wands don't have the Display As Attack customization checkbox.

They test new stuff on paid subs first before rolling things out site-wide. 🤷‍♂️

Well, then I'm a proud guinea pig.

I think they must have fixed it in general, because I'm not paying for anything and both this and a couple random older staffs from older books work for me now.

 Cool!

But also why I hope the OP can provide a character link, since something else might be going on (maybe it's a homebrew, or a Beyond20 interaction.)

Here is my character.

I see the Staff of Striking in your Actions tab, right below Quarterstaff. Does it not show up for you? Or does it lack a Hit / DC die roll?

Are you using any browser extensions such as Beyond20?

Edit: Looking at it in the sidebar, the Staff doesn't have To-Hit and Damage die details, since it's technically a staff, not a magic weapon. I recall Beyond20 turns those details on weapons into die rolls. Is that your problem?
