Polygon POS - Mostly empty blocks

For the last 8 hours the Polygon POS blockchain has been producing mostly empty blocks. For example: https://polygonscan.com/block/34547344 and https://polygonscan.com/block/34547386 but there are many many more. I ballpark at least half the blocks is empty - if not more. Is there any indication what is going on? Seems to be some consensus issue. Would appreciate any indication of a solution so we can plan accordingly.
