Would love to have an epub reader in Edge chromium as we had in the Edge browser. Really loved the reader there. @Elliot Kirk
Unlikely to happen:
ePub support ending in Microsoft Edge
Microsoft Edge will end support for e-books that use the .epub file extension over the next several months. For more information, see Download an ePub app to keep reading e-books.
