I need the latest version that still supports the Surface 4th generation. It seems that the 2021 cycle doesn't provide this support anymore. The last version I used was 2020 R2. Honestly, it annoys me that as manufacturer team you don't see the problem.
Strange, now it installed without complaining about the machine being outdated. Anyway in truth in the past, I had also the same problem as you dropped the support of the HD 4400 or similar, luckily is not in our targets anymore.
