LTE Internet just not working well at all (Cradlepoint)

XG-7100 PFsense Firewall
We are currently relying on LTE internet from Verizon to run the business till fiber is installed. Since I have installed these(2 weeks ago), we rarely can connect to the web. Pinging works without issues. When you run a google search, most of the time it loads. If you go to a website, it comes with the “this site cannot be reached”. Sometimes if you let it sit at that message, it will try loading again and works.
If I connect my laptop directly into the CBA850, it runs great, but as soon as it connects to our PFsense firewall, the issues come. I have 20 users, we use Outlook, and not heavy users of the web as most of our stuff can be done internal thankfully. I can rule out its my switch as the same issues come up if I plug my laptop directly into the firewall and try accessing the web.
Any idea on where to start looking? I feel like I have tried everything including: changing the MTU from default to 1428, resetting the state, and much more. I’m open to anything.
Below are pictures of my current configuration. Let me know if you wish to see anything else.
