Fixes and workarounds

Fix

ProductFix versionIBM Security QRadar EDR3.12.27 The IBM Security QRadar EDR operator can be upgraded automatically when new compatible versions are available. However, you can control whether an operator is upgraded automatically by setting an approval strategy. Two approval strategies are available: Automatic (default) - New operator versions are installed automatically when they are available on the subscription channel. Manual - When a new operator version is available on the subscription channel, the subscription indicates that an update is available, but you must approve the update manually.
