Galaxy Tab S3 suddenly can't support SD cards

After the Sept Update (now shows "Software update to T827VVRU3CSH4), my Verizon Galaxy Tab S3 stopped "supporting" the SD card that I've been using for the past year or so. It now does 1 of 2 things for all SD cards: 1. Displays a message "Unsupported SD card". "This device doesn't support this SD card. Tap to setup in a supported format". I've tried formatting the same, previously working SD card a few times now, but no luck. I've also tried 2 other SD cards, but they too cause the same, repetitive formatting prompt. 2. Doesn't recognized at all Has anyone else experienced this recently? I'm wondering if it might be a bug in the recent update, or something specific to my tablet + SD cards.
