I've been using the ribbon workbench to make a free solution for people that need to send Birthday Text. I've added a custom activity entity to the Account Ribbon called: "Send Text", but here is the problem:
In my original solution, the form ID was "etc=10019", but after I exported the solution and imported it into a new CRM Online instance, the form ID changed to "etc=10018", this means that the button no longer works. I'm sure that I am doing something wrong here because I have seen other people deploy solutions similar to mine, and they kept their custom button working. I'm hoping this is not a bug in Ribbon Workbench as I just re-installed a new copy.
