Unable to use T-Mobile Home Internet with work VPN, any suggestions?

Let me first say that I’ve been a T-Mobile fan boy ever since I signed up.  

When I first got TMHI, it worked like a champ.  My wife logs into PaloAlto GlobalProtect everyday. Worked.  Worked better than my previous fiber connection which seemed to need too many reboots to work, which is why I moved to unwired internet.

Then out of the blue, VPN stopped working, but EVERYTHING else still worked.  Naturally, I thought it was the VPN issue. Called into TM support, and was told it was an issue between GlobalProtect and TMobile and that they were working on it with no ETA.

I started Googling the issue and found that there were numerous complaints about the same problem in this community. I tried everything that has been suggested with little success.  The most success I had was yesterday.  I decided to factory reset my Sagemcom. When it got to the part when the app asked me to update, I closed the app.  I checked the connection to the VPN and to my surprise, everything worked.  Outlook, TEAMS, the internet, and everything else my wife logs into. It worked for about 4 hours.  Unfortunately for me, I had posted on another thread about what I did to get it to work and what I thought about TMobile's culpability about it.

After about 3 hours after I posted about it on the other thread, the troubles started again. Not only with the gateway, but my Linksys mesh network connected to it, which was a first. It's possible that my Linksys issue is a coincidence.

So, I've got opinions. LOL. First, I think it's pretty repugnant that TMobile would let us sway in the wind like this.  They have known that the update they pushed to our gateways caused the VPN connection issue. I suspect it's gotta be a business decision.  They probably didn't foresee how many users were going to use their service to connect to their work VPN servers.  There must be a great amount of data that is being used. If it was the VPN companies issue, why was I able to login to their network and use it flawlessly for so long? When I did start having trouble, there was a message on the gateway stating that there was a problem and to reboot? Also, I imagine that a T-Mobile moderator cruises these threads and I may have opened myself up to a targeted whatever you wanna call it. Again, I could be reaching.

Anyway, I'm very disappointed in how TMobile has dealt with this. I don't like being lied to. If they had any intention to fixing the issue, they would have pushed a firmware patch weeks ago. I do not buy the "we didn't know" or "we just found out and we're trying to fix it" pitch. 

Good luck to the rest of you.  I moving on to a different provider.
