Bluetooth connection issues with KB7120W and XPS 13 2in1

I purchased the Dell Multi-Device Wireless Combo to go with my new XPS 13 2in1. The mouse works great; it always stays connected even after wake-up and reboot. The keyboard, however, constantly disconnects on wake up or reboot. Basically, the keyboard shows up in devices as paired, but not connected; I have to disconnect the device and add it back and pair it each time. I tried the Knowledge Base and did not find anything. I called support and each support rep. that talked to said that they would connect me with the person who would be best to talk to; after 4 reps and waiting 3 hours, I hung up. I thought it might be a Win10 ver 2004 issue so I went to the MS Win10 community and posted the above details and got a reply that linked article 403457. I did read and tried some of the suggestions. I then replied the following:

"After more than a week, it is still not connecting well. Most of the time I have to delete the device in the "Mouse, Keyboard and Pen" list and re-pair.  That process usually goes like this:

1. In settings, select Devices.
2. Under the "Mouse, Keyboard and Pen" list, select keyboard and click "Remove device".
3. Click on add device. On the "Add a device" screen, click Bluetooth.
4. Press link button on keyboard until the channel 2 light is on and press again until blinking.
5. Wait until the keyboard shows up on the "Add a device" list, then click on it.
6. At this point one of the following things will happen:
7. 1. You'll be asked to add a PIN on the keyboard (don't forget to press enter) then it says your done. Go to 7.
   2. You'll be asked "Try connecting device again".  Sometimes it works. After trying 3 times, I reboot the computer (in this case a new DELL XPS 13 2in1) and then start at item 1. again.
8. At this point one of the following things will happen:
9. 1. The keyboard shows up on the "Mouse, Keyboard and Pen" list as Connectted. Done!
   2. The keyboard shows up on the "Mouse, Keyboard and Pen" list as Paired. Try pressing the link button on the keyboard until channel 2 light is on and wait up to a minute or so, if it shows up on the list as Connected: Done!
   3. 1. If not, turn the keyboard off, wait 30 seconds and turn back on.
      2.  Go to item 2.
   4. The keyboard does not show up on the "Mouse, Keyboard and Pen" list: Go to item 2.

The mouse that came with it connects automatically every time. I would like the the keyboard to do the same. Windows 10 home says it is up to date. Windows says the drivers are the best drivers for the device. Dell website says I have the most updated drivers. I am still trying to figure out if this is a Windows 10 Home (ver. 2004) issue or DELL hardware/software issue. I was on Dell support call for three hours mostly on hold as each of the three or four people I talked to said they would forward me to the person who could best solve my issue. After 3 hours, I hung up."

Does anybody here have any suggestions?

Any help in this area would be much appreciated. Thanks
