Problems
I would like to know the max limit registrations of Universal Links. There is no information about the limit in the latest documents, how many links we can register.
Background
Now we consider introducing UniversalLinks to our application and one of the requirements is registering multiple domains. In the system's specifications, there is no upper limit.

Archived documents say as follows but I don't know this is a reliable resource.
In your com.apple.developer.associated-domains entitlement, include a list of the domains that your app wants to handle as universal links. To do this in Xcode, open the Associated Domains section in the Capabilities tab and add an entry for each domain that your app supports, prefixed with applinks:, such as applinks:hogehoge. Limit this list to no more than about 20 to 30 domains.
