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

Since the last firmware update (4.10.1.27) 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.
