Same issue here. I've never had a problem renewing over the past 4 years. After my most recent renewal in September 2020, I continue to see "Expired - temporarily extended" on all of my computers. I've applied the new license key, the old key, used the removal tool exactly as instructed. Days later, I still have the same issue.
Maybe it has to do with my account showing licenses for old products. They are:
Malwarebytes 3.0 Premium (formerly Anti-Exploit Premium)
Malwarebytes 3.0 Premium (formerly Anti-Malware Premium)
Can someone in support get rid of these old products and update them with the current product and the same number of licenses (6 total computers)? Maybe that will fix the issue.
If my computers eventually revert from "temporarily extended" to "free", I'm finding another product.
