While running trials of TimeXtender it is fairly common to run against SQL Server Developer Edition. As SQL Server 2022 has been GA since last November, this is the version people will generally be installing.
Finding 2019 is fairly hard. I have noticed that the 20.10.37 ODX Server is perfectly happy, but that TimeXtender 20.10.39 gave me an “Unsupported version of SQL” error, even with databases running in SQL 2019 compatibility level. Is this supposed to be the case?
Azure SQL DB is 2022 under the hood, even if SELECT @@VERSION states something else.
