Blink mini -> working, Blink outdoor -> not working

Hey all, Iam running out of ideas, so maybe someone here can help me. I have a

• Blink mini (the small white one, indoor)
• 2 Blink outdoor (black, batterie powered, outdoor)
• and a sync 2 module.

Up to today i only used the Mini and one of the outdoor cams combined with the sync 2 module (without sub).
Everything was working as i wanted. Both detected movement, both wrote the data on the usb stick in the sync module.

Today i activated the 2nd outdoor cam, and with that i got one month of free sub and because of this everything was saved on the cloud for 30min before I realized it. I canceled the sub and set the sync 2 module back to local storage.

Now the Mini Cam is saving (as it should) to the local usb stick. Both outdoor cams detect the movement (blue led on) but don't save the data anywhere.

I deactivated / activated local storage again, power-cycled the outdoor cams + sync module, restarted the app - nothing helps. Even deleted both outdoor cams from the app and added them again - still nothing is saved.

thx for any idea :)
