The DNS-authenticator in the TrueNAS web UI (at Credentials -> Certificates)? No, I haven't seen that. Losing it in clusterissuer or the Truecharts apps? Yes, that's expected behavior with the update that rolled out at the end of last year:
We're glad to announce that shortly we will release a big update to all our Apps. This will be a complex update that technically includes a few changes that might break some specific features for some users. While we do not foresee any data loss, it's imperative to back up your data.
