Reduced redundant page-state updates and drawing-toolbar switches while scrolling PDFs, improving scrolling and handwriting performance.
Fixed recording deletion confirmation messages that did not include the recording filename in some languages.
Restored CoreAudio compatibility for Mac Catalyst.
Made backend refund processing atomic and idempotent, preventing duplicate AI-point deductions, retained Pro access after refunds, and inaccurate restoration after refund reversals.
