In my particular situation because the installed module was an old Dev version it was not picking up an update. I was advised to change the module version number to 10.0.1 in sys_modules table. After this was done the update to 10.2 appeared and it was just a matter of clicking updates as the incremental numbers popped up in the updates. I clicked through and am now at version 12.0.1. This fix by Alex T⚜️ worked for me.
However, I do not recommend that you do this for any other modules without getting guidance from the UNA team. In my case it work but if you have other modules or situations - DO NOT use this without guidance.
