Using 73.0.1 (64-bit). Good Twitter still working, but have message at top of page saying "You’re currently using an unsupported browser — for the best Twitter experience, please consider updating to Windows 10, or check the list of supported browsers. " Many threads reporting same issue in Chrome.
