So was this taken as a bug report as people were obviously testing with those pre-release versions? It is now the time of the general release of this supported operating system and you are not compatible. Most developers use beta periods – or at least the time from release candidate on – to insure they are solid before the new OS version goes wide. What is the ETA for the fix now that this issue is active on production release of a widely used operating system?
