Quote:Microsoft removed a compatibility hold after fixing a known issue that would lead to Qualcomm Bluetooth radios having issues discovering and connecting to Bluetooth devices because of outdated drivers after installing or updating to Windows 10 1903.
 
Redmond applied the update block on May 21 to prevent devices featuring affected driver versions for Qualcomm Bluetooth radios from being allowed to install the Windows 10, version 1903 or Windows Server, version 1903 updates until the driver has been updated.
 
The Qualcomm Bluetooth discovery and connectivity issue has been resolved with the release of the KB4517389 cumulative update.
 
While the safeguard hold has been removed, customers should know that "it can take up to 48 hours before you can update to offered Windows 10, version 1903 or Windows Server, version 1903."
