YAY!!! v3.0.1 is now live
Are you sure it doesnt support it and its just that your instance did add the proper field to the API (it isnt there by default)
Pretty sure its relatively new, like 6 months ago or something they added it
keep any eye out for any features you see and like on other instances. I can usually track down their changes and extract it pretty easily now I think.
@design_RG or @mngrif When ya get a chance can you see if our character limit is now working on mobile?
