Dozens of thousands of accounts can't access the Toybox API

It’s been 3 weeks since the new Toy API feature was implemented and released.
There are dozens of thousands of accounts (roughly about 2%, or 20k-28k of the 1.1 mln scanned) with no working access to it.
Are there any steps toward solving this problem?

I managed to create a new account, this solved the problem temporarily.
