A day for April to end and the April security patch update is finally available for the Nokia 8 Sirocco. Fortunately enough, the update is a maintenance release and does bring some bug fixes alongside the Android security patch. The changelog mentions Improved system stability and User interface enhancements.
The update is 353MB in size. It should be available across several markets, but some (as usual) may get delayed due to regional certifications and operator interference.
If you are sporting a solid stainless steel Nokia 8 Sirocco, then it is the right time to check your device for software updates.
