Instagram Video Not Playing on MacBook Air in Safari, Chrome
This issue began on or about August 1st. Instagram videos do not play on MacBook Air in either Safari or Chrome. OS Big Sur is updated. Caches emptied. After most recent update and restart, video played once, slowly, then no others would play. Clicking videos gets either a frozen image (Chrome) or black screen (Safari). Everything fine on iPhone 12.
MacBook Air 13″, macOS 10.13
