Mouse and Keyboard irrisponsive on brand New Mac mini M4!

Just got the new Mac mini M4. Keyboard and Mouse is quite irrisponsive/delayed unfortunately. I experienced the same on Imac M1, but never on my Imac 27" i7 Quad core or any of the old Imacs or Mac Mini's or older laptops I have. The Keyboard I use is an Apple Magic Keyboard, the Mouse is a Logitech BUT it is connected with its on dongle, and does not make any delays on any my other Macs (includes two older laptops). It is quite anoying, what to do?
