I have been experiencing this issue for months, and due to our critical infrastructure, we cannot switch domain registrars quickly.
I have had my domains registered with Google for years and never encountered any problems. However, after the acquisition of Google Domains by Squarespace, all domains were transferred to Squarespace. Since then, we have been unable to create any wildcards. This is not just a missing feature; it is critical because it prevents us from deploying our QA environments.
I have contacted support multiple times, but the only response I receive is, “Our engineers are working on it.” As one of the largest domain registrars, I expect Squarespace to handle such issues promptly and professionally.
This situation is highly frustrating and unprofessional.
