If you are using Briq with slack and the Briq's commands are not working anymore, it's probably because our access token to your slack needs to be updated. Several reasons can explain why this token has expired, including the fact the person who initially installed Briq left the company (and thus the slack). In this cas, an admin needs to set up Briq again through this link. This process won't affect neither your usage of Briq nor your exchanges history.
If you are not using Briq with slack, please contact us.
