Sometimes it will work, sometimes it won't, but it always ends up failing after a few attempts. I am able to roll dice only in DnD beyond, no matter what extensions (or combinations thereof) I use. 

This is really interfering with my campaign, and it seems to have become a problem only within the last few months. We didn't run in to this issue at the start of our campaign in June. 

Please help! Google searches on this topic give me nothing. 

you realy should ask the talespire developers about this, dnd beyond does not support any external vtt
