Confirmed, 3D dice rolls show up for the roller, but not the other players in the game when making rolls from the D&D 5e 2024 by Roll20 character sheet. Reproduction: Open a character using the D&D 5e 2024 by Roll20 character sheet. (Note: using Jumpgate) Enable 3D dice for the roller (player making the rolls). Also enable 3D dice for the observer (player not making the rolls). Have the roller roll something in chat (not from the character sheet). Result: roller and observer both see 3D dice. Next, have the roller use something on the character sheet (skill, ability, attack, whatever). Result: the roller sees 3D dice, the observer does not. To notify the Devs I suggest filing a bug report via the Help Center as the bug report forum is primarily community support.
