Most problems are one of the five below. If yours isn't, email me — a real person reads it.
Including a diagnostics report makes almost every problem solvable in one reply — see below for what it is and what it leaves out.
A tab that was already open before you installed or updated the extension needs one refresh before it can be rotated. Chrome does not inject into existing tabs retroactively. Reload the page and try again.
Chrome blocks every extension on chrome:// pages, about: pages,
the Chrome Web Store, and PDF viewer pages. That is a browser rule, not a limitation of this
extension — no extension can run there. The popup will tell you when you are on such a page.
Rotating a player inside an embedded frame requires running inside that frame, which needs the optional all-sites permission. Turn on Rotate videos, incl. embeds in the popup and Chrome will ask once. Decline it and the rest of the extension keeps working exactly as before; you can revoke it later in Chrome's extension settings.
When Chrome asks what to share, choose This tab. Picking "Entire screen" or a window cannot be cropped to your region, so the pin is refused rather than quietly mirroring your whole screen.
While the pinned area is scrolled off screen — even partly — the panel holds the last full picture and says PAUSED · last frame. That is not a bug: Chrome only draws what is on screen, so there are genuinely no live pixels of an off-screen region to show. Scroll it back and it goes live again. A pinned video keeps playing regardless.
Chrome assigns extension shortcuts on a first-come basis, so another extension may already
hold them. Open chrome://extensions/shortcuts to see and change them. The
defaults are Alt+R to rotate right,
Alt+Shift+R to rotate left, Alt+0 to
reset, and Alt+S to pin a region.
$7.99, once. Not a subscription, and there is nothing to cancel. Reading Canvas and Dance Study run free for 60 seconds each time you open them, so you can see them work before you decide.
Open the popup and click Restore in the footer, then sign in with the email address you paid with. Your purchase is tied to that address, not to a device.
Email me. If the extension didn't do what the listing said it would, you get your money back — I would rather refund you than argue about $7.99.
The popup's Copy diagnostics button copies a short plain-text report to your clipboard. It contains structural facts — extension and Chrome versions, the current angle, window size, how many videos and frames the page has, whether the site's own CSS fights the rotation — and it deliberately excludes the page's address, title, text, form values, links, cookies, your settings, and anything about your account or payment.
The site's address is included only if you tick the box, and then only the scheme and host — never the path. The box is off every time the popup opens. You can read the whole report before you paste it; nothing about it is stored or sent anywhere.
