No Sherlock, he's talking about the self analysis board to test out lines during a game, not an engine.
Premium membership is not a requirement for the self analysis board (although it is a requirement to save that analysis).
Please state what device or app., you're using.
I'm on an android mobile via Samsung web browser, and I've no problems with that feature.

Okay, I think you are accessing the site through an internet browser & not an app., try upgrading your browser or try a different browser.
Also I'm not sure, but maybe it's possible that an aggressive ad-blocker might interfere with this functionality, so try turning it off.
If this doesn't work then try downloading the latest version of the app., it solved a similar problem here (let us know what works):

Sorry apart from a work computer, I've not got access to a PC or Windows, maybe someone who has can help more.
What level membership needed to get the analysis board on the correspondence games working? I've always paid for diamond but hardly ever used the features it offered, but notice now I can't use that convenient little board since I haven't renewed. Thanks
