There are no devices to display

Is anybody else having the same issue as me where you cannot access the devices that are connected to your Wi-Fi through the T-Life app? I have tried everything multiple times (rebooting my router, uninstalling and reinstalling the app, factory resetting my router). And, yes, I’ve spent endless hours talking to customer support and they have zero solutions. I did a factory reset on my router yesterday and all my devices - connected and offline - showed up briefly, but have since disappeared, so I am yet again getting the “There are no device devices to display” message in the app.
