Does anyone have the EE Smart Hub Plus Router?

Wondering if anyone has the router above - received it recently and it doesn’t seem to allow Ethernet cables to click into the Ethernet ports on the back of router. Maybe I’m being daft/having an absolute nightmare!! I’ve got a few different Ethernet cables that I’ve tried, but no luck. It’s not a massive issue as the connection still works via the cable, however they’ve come out of the router a couple times if the cable is knocked given they’re not clicking into the ports. Just wondered if anyone has encountered this?

Thanks very much!

Reading online seems fine to plug into the router.
What is connected at the back?

As a temporary fix you could break off the clicky bit on the ethernet cable as unless it clicks in will assist the cable to come loose.
