Citrix Workspace app issues

I'm having horrible Citrix issues but it appears to happen only when connecting to the interent via T-Mobile's system.  At home, I have the t-mobile home internet.  Originally, I had no citrix connection problems with this system but since around September, I started having issues.  While in the past connection problems were more sporadic, now they are persisistent, daily, practically unresolvable.  This happens whether I connect through the t-mobile HI gateway via wifi or via cable.  

Today, I tried connecting my laptop via wifi to my t-mobile iPhone after setting it up as a personal hotspot.  Again, Citrix workspace app desktop client simply would not launch. Ever.  Then I got to the office, connected to office visitor wifi, and ran the login.  On the office wifi, Citrix workspace app desktop client launched successfully, flawlessly, seamlessly on the very first try.  0 issues.  Thus, it's pretty clear the problem is the t-mobile system.

NOTE: The office wifi has about ½ the download speed of t-mobile personal hotspot router (150mbps vs as high as 486mbps), twice the seek time (59ms vs 29ms), but still works just fine.  This definitely looks like a t-mobile system problem, not a personal laptop problem!  Exact same PC, 20 minutes apart, success on first try when not on t-mobile's system vs 30 minutes, 100% failure, when using t-mobile to get to the internet.  Fix this now, t-mobile, or I'll find other providers.
