About 3 weeks ago, our company started rolling out the Lenovo L14 model to replace our Dell 5480 models. The laptops were sent out to a couple of remote users and soon after, we started getting complaints that the users couldn't start or accept meetings on their zoom app or even browse the zoom.us website. We do have split tunnel configured by (app & domain) for zoom, and they worked fine on our, Dells, MacBook's and other vendors., so we knew that the configs were correct. We even did traceroutes, Packet captures and added all the Zoom IPs in the split tunnel exclude access route and they all confirmed that the traffic was not going through the tunnel, so split tunnel was working as configured. Even a brand new out-the-box Lenovo L14 still didn't work with split tunnel enabled.
