The Twiddler Tutor has never worked for me in iPadOS’s version of Safari (it consistently loads a partial, unformatted page and is unresponsive) but (until yesterday) has always worked with iPadOS Chrome. No longer. Under Chrome, the Tutor page now comes up formatted but incomplete and is unresponsive. I’d be interested to know whether this is a personal problem or if others are experiencing it. Many thanks.
