Delayed Notifications for Nanit

We have 2 Nanit Pros (have had 1 for 3 years) and just recently started having issues with delayed notifications for sound and movement. There is anywhere from a 5-15 minute delay in the event and the notification arriving on any of our devices. This issue exists across multiple iOS devices and both Nanit cameras.

When I look at that activity log in the camera, the detections/events are there, however, the notifications are not being delivered in a timely manner.
