Adobe Indesign Server CC 2020 Crashes and takes longer to process

[#1]

Observed that CC 2020 Desktop too had issues but using the latest version of 15.1.1 made it work. 
I just want to know do we have any update for server too as the same template processing in cc 2109 server is proofing in few seconds but the same template when proofed on cc2020 takes more than 5 minutes and some times crashes, indesign server automatically goes into hang state and we have to kill the instance and make it work.

Any help on this would be greatly appreciated.

Thanks

Do we have a latest version of indd cc 2020 server or is it just 15.0?
