Confluence Cloud: using Requirement Yogi traceability matrices as input to Table Transformer

[Goode, Steven]

We currently use Data Center, and get a lot of value from applying the Table macros (Table Filter, Table Transformer, Pivot Table, etc.) to Requirement Yogi data from RY Report macros. 

On the cloud, RY Report will not be available. We tried wrapping Table Transformer around an RY traceability matrix, and Table Transformer didn't recognize it as a table. Table Transformer's support said this is a problem with how Confluence Cloud uses iframes.

Has anyone else faced (and fixed!) this issue?
