No luck for me, the message is still there after the update.
EDIT: nevermind, I just had to clear my cache. Thanks! 
Music to my ears. After taking a second look I should be able to fix that issue where you canβt update MEC without disabling first. Stay tuned and have a great day.
That would be amazing if we could auto update!
Thank you
I can report the same experience. I had to deactivate the plugin, update it from the update screen, and then come back and reactivate it.
At that point, the error was still showing, but I cleared all caches, including object cache, Cloudflare, and any other WordPress caching plugins i had active. And even then had to do several hard refreshes on my browser cache before the activated license message in green showed up. But Iβm pleased to say it finally did!
Thanks @charlie! Hopefully we can update this plugin moving forward without having to deactivate it, and hopefully this licensing fix carries with any future updates.
The update issue should be fixed in Pro 6.9.7. Let me know if you see otherwise.
Just about to try it now, will let you know
It Worked!
No more deleting MEC to reinstall it, honestly this is one of my favourite updates to Pro this year (and there have been some good ones)
