On the calendar cancel booking page (widget/cancel-booking), the appointment date, time and time zone are crossed out as soon as the page opens, before the client enters a reason or confirms. Clients read it as already cancelled and aren't sure whether they still need to submit. A client of mine pointed this out after cancelling. Please show these details normally until the cancellation is confirmed, or add a setting to turn the strikethrough off. Calendar custom code doesn't load on this page, so there's no workaround on our side.
