NOT a Smarty issue - Any issues like this, โDown Detectorโ should be your first port of call, and yes, WhatsApp has been experiencing issues in the last few days. WhatsApp servers are part of the same server farms as sister services, Facebook and Instagram, who are all owned by parent company, โMetaโ
Not scientific by any means, but the weekend just gone was the three day โMemorial Dayโ weekend in the USA, including yesterday, Monday, so I imagine there has been a lot of traffic through Metaโs servers in the last 72 - 96 hours.
