When Comcast has new, update or improvement design, layout and/or features they should aptly first send emails to all subscribers asking us what one(s) amongst we like, dislike, want or need to let us customize, tailor and choose exactly which is or are suitable individually for us instead of Comcast very badly forcing changes on us such as their latest total disastrous lousy resulting outcome email base server that began January 1, 2018 changed, I liked how everything was that I last saw December 31, 2017 intact. Along with this Comcast should display a click button key or provide visit link address to do at opt New/Current/Present or Old/Original/Former email base server design, layout and features version or format - I have seen this knowing existent elsewhere available thus Comcast can likewise implement too. I do not want to resort to using some other email base server nor email download client to write, send, receive or relay from, I want to stay at Comcast email base server completely and normally throughout. I use to like using Comcast email base server, now I dread going there and can not find anything to even make a slightly adaptable compromise, sacrifice or tolerance use as-is in this particular massive disappointing case.
You can't revert to the old format once you've been migrated. Did you have a question about how to do something in the new format?
