Iframe with external protocol was blocked due to lack of user activation, or because not enough time has passed since the last such iframe was loaded.
Cafodd Iframe â phrotocol allanol ei rwystro oherwydd diffyg gweithredu gan y defnyddiwr, neu oherwydd nad oes digon o amser wedi mynd heibio ers i'r iframe olaf gael ei lwytho.
