Logitech Pebble M350 Scrolling issue on iPad

Hello everyone.

I purchased Logi Pebble M350 mouse for my iPad Pro 12.9 2nd gen. After watching lots of videos its good for this device I decided it will be this mouse. Anyways I am having issue with scrolling.

After I open new window the scrolling is not working, I have to almost every time click with the scroll button on window I want to scroll in order to force it to work.

This happens on safari, but as well in whole iPadOS system. I go to iPadOS settings - scroll is not working, I have to scroll-click on window where is scrollbar and only then it works.

On safari for example, Im looking through google search results, after I click on any result text, scrolling stops working. I have to click on empty space with scroll.

Its really annoying and confusing. Like iPad was not able to automatically tell the mouse what is active window or something… Is there any solution for that? Do you have same issues?

I have latest iPadOS. Sorry for my english, I wrote this in rush, while I got confused working on the iPad…
