Pairing a new Logitech mouse with non-unifying receiver

I have a Logitech keyboard and a mouse pair (keyboard K270 and mouse M185) that are paired to a single non-unifying receiver, and they work (I bought them together as a pair). Now one button in the mouse stopped working so I bought a new M185 mouse, but I can't pair it with the older receiver using Logitech's Connect Utility (version 2.30.90). I do as the instructions say (turn it off then on again) but the utility doesn't recognize it (I tried this strategy to re-pair the older keyboard and it worked). The new mouse works with its dedicated receiver that came with it, so I know that the mouse is OK. But why can't I pair it with the older receiver (with or without the keyboard)? I also tried pairing the keyboard with the new mouse's receiver, but failed (the Connect Utility doesn't recognize that receiver at all - it says no receiver is connected - although the mouse is working just fine with it). Is there any way to pair the old keyboard and the new mouse with the same non-unifying receiver? What other alternatives do I have besides plugging to receivers simultaneously?

Try different peering software - support.logi.com/hc/en-us/articles/… is, I believe recommended.

@davidgo - Same problem. With the keyboard's receiver, it won't pair the mouse, and with the mouse's receiver it won't even recognize the receiver (again, although mouse is functioning)
