Who I have the same questioned this topic

Hi.  I have a network extender 2 for enterprise.  Across multiple devices, SMS messages are delayed for hours.  When I disconnect the extender and use WiFi calling, there are no issues with SMS messages.  Voice calls with the extender work flawlessly.   My internet connection is solid (1G/1G fiber).  Are there problems on the verizon network causing this?  I would really like to use this rather expensive extender but not receiving texts is very problematic.
