CAN YOU MAKE TOAST MESSAGES ACCESSIBLE?

Summary from the TLDR Design newsletter

GitHub's design system banned toast messages because they create accessibility and usability problems that can't be fixed with technical solutions. Toast messages disappear automatically after a few seconds, obscure underlying content, and are difficult to spot at the edges of the screen. GitHub's usability testing with disabled users showed that fixing these core issues requires changing the pattern so fundamentally that it would no longer qualify as a toast message.
