Tamron 28-75

Hello everyone. I’ve been using a Tamron 28-75 f2.8 on my A7rii for a few years. Starting last night, it stays on 2.8 even when I zoom in. It would be great if that was true, but surely something is wrong. Anyone else hear of this happening? My Sony 70-300 still adjusts the fstop as it zooms.

Thank you
