Hi,
everything is normal.
I think first you need to read this article:
https://techcommunity.microsoft.com/t5/discussions/microsoft-advisory-shows-whether-edge-keeps-up-wi...Here is the Changelog for Edge stable 80:
https://docs.microsoft.com/en-au/deployedge/microsoft-edge-relnote-stable-channelChrome is version 80, after 3 days, Microsoft released Edge version 80 too. they HAD to, because each update fixes serious security vulnerabilities.
and it was most likely the first and last time Microsoft did it, only to align themselves with Chromium release cycle and stay up-to-date with the security patches inside Chromium builds. going forward, Microsoft will stick to their correct release schedule which is every 6 weeks, just like Chrome.
currently, there is a 3 days gap, so after Chrome 80 was released, Microsoft released Edge 80 3 days later. I hope next time it won't be that much and comes down to 1 day.
