Pan cams locking up and not connecting with MicroSd card since last update

Since the last firmware update ( my two Pan cams will lock up and don’t connect in the IOS app when a micro SD card is inserted.

When I remove the card they work fine. Both cams have been working with these cards perfectly for over a month.

I got the sd card a week after the camera. put it in and worked fine for 24 hours. now says no sd card and it is clearly there. I havw ejected and reinstalled several times. also deleted and restarted cam but still says bo sd card. help!!

I was able to reformat the cards in my Mac using the SD Card Formatter and now they work again.
