Agreed, friend. The changes have made Medium largely unreadable. I really do hope they have the integrity to give you a refund (but wouldn't hold my breath, personally).
I now only use the platform to post news and reprints, and have no plans to renew my membership.
It's increasingly difficult to find one's favorite writers (yourself included) but I'm still hunting them down when I can.
I million thanks for the coffee, by the way. These are stressful times, and every drop helps.
Here's to a better--and creative--New Year.
