Iframe embed sizing

Hi there Guys!

While utilizing the given embed codes to my scores:
Transport bar is truncated. Meaning that the critical buttons like play etc. are fine, but others like print and especially in my case, tempo are inaccessible in the embed window.
This may be intentional, or something, but sure would be nice if my students could slow down the score on my site.
-- I have tried various iframe size parameters, and no luck.

Meanwhile, other features, I'm sure you know, seem to be now only acessible through the ap-store? I recall having used them a couple years ago, without getting the pop-ups that direct to google-play, etc.

Thanks!

PS, I hope I placed this in the proper forum?
