SmartHub VMB4540r3 no firmware upgrades

[Chandler88]

Hi

My smarthub stays at an old firmware version (1.21.1) and I cannot figure out how to upgrade it. 

Things I tried:

* restart the hub

* used my.arlo to search for new versions (it says „no updates available“)

* removed the hub from my account and added

it again

* factory reset the hub, removed it from my account and added it again

the reason I want an upgrade is because the local storage is not working really good. Once I format the drive it works for a few recordings. Soon it stops working saying that there are no recordings found. I have no subscription. I tried support, but without subscription they won‘t provide useful information. 

thanks for any hints
