Twitter Fetcher + Stacks 3?

Twitter Fetcher in Stacks 3 seems to be broken - anyone else experiencing this?
Just upgraded my site to latest Stacks 3 and Foundation theme and published a test - seems the Twitter Fetcher is not working (was fine in Stacks 2).
Have sent the developer (Weaver Themes) an email but it appears they are on holiday till 7th Sept.
Anyone have any help or ideas?

OK Vitor at WeaverThemes has now issued an update to the Twitter Fetcher stack and it’s back working again.
