We are using DnD-Beyond and Roll-20 

For the Last couple of weeks Class attacks are just not rolling dice. 

I'm a Kensai Monk and if I attack with Longbow or Katana (a rebadged Longsword) the Dices roll in DnD-B and come through to Roll-20 as it should. 

If I click on the fist symbol to attack all I get is the item info panel ... no dice roll on either DnD-B or Roll-20.   If I try the individual roll to attack and roll damage again I get nothing.  If I use advantage / disadvantage option I still get nothing.

It's not just me ... every one in our campaign has the same issue with class based special attacks.  Standard weapon attacks work but nothing else does.  Started happening 3 weeks ago and we assumed it was a bug that would get fixed .. .but it's still here.

Has anyone found a solution?

Your issue is the Beyond20 extension. 

Anything specific about the extension?   I've looked, and updated but still no joy on what might it might be IF THAT IS the case

D&D Beyond does not provide support for third party extensions

Please contact the developer

Alternatively disable and remove the extension
