DumaOS not loading apps Telstra Smart Modem 4

[internet-]

Using Telstra Smart Modem 4 with Firmware SGPE1TL0104AA-1.0.32A

DumaOS Version: 3.3.754

The Router Apps inside DumaOS do not load, on Dashboard, only the Traffic Overview panel is loaded, with an error popping up stating Could not load app

Device Manager does not load.

Resetting modem and restarting modem sometimes temporarily brings back Device Manager, but it’s extremely sluggish, then fails again.

Error message displayed: Error: This Router App is not loaded yet, please try again in a minute.

Network monitor, network rules, network priority apps do not load either.

Adblock, Ping map, Geo-filter, Connection benchmark are working 

[Netduma Fraser]

Please try de-activating and then re-activating the optimiser package and see if it works properly after that
