Embedded YouTube videos are now shrinking when viewed on an iPhone (but not on an Android), rather than filling the width of the page. This also applies to historic products, which (until no earlier than three months ago) had previously outputted in in5 without this problem. The Advanced export settings are 'Use Desktop Scaling / Fill Width'. If I change settings to Zoom to Page Width, it solves the video scaling issue, but the navigation bar and buttons, etc. are then too small. Please can you help? Thanks.
