Tech support?

how do I find technical support for the Adobe Express product? I don't see any help buttons or chat in the product.

Here is my issue...

I get the following message since Friday of last week for all my Instagram posts I'm trying to share via the scheduler....."As this technical issue is less common, our team will need to look into this to identify what went wrong."
Since Friday of last week, no posts have successfully been posted through the scheduler, and this error shows on each post.   
Yet I do not hear from adobe tech support in regard....  Please advise.

Thank you,

Rick
