Hi Tounizino
Thanks for the comment.
So we can look at the issue, can you tell me how you are using it?
Currently the buttons should work without issue if using the classic editor plugin.
However, the classic editor block (in Gutenberg) has some bugs to be resolved.
We are hoping to mitigate the need for this by releasing a version with Gutenberg integration (FASC buttons will be available in all the blocks you use), however, there is a bug in Gutenberg (which has been fixed) but has not yet made it to a WordPress core release – it should be available in the next couple of weeks.
Anyway, interested to hear your use case and if its something we need to look into further.
Thanks
