Lenrich keyboard

I just bought a new IPad Pro 12.9 and a Lenrich Bluetooth keyboard to go with it. I had the IPad Pro 2015 previously also with a keyboard. This is so aggravating, but the iPad can not keep up with the keyboard. So, it ends up putting periods everywhere, double spacing everywhere, and if I try to use a comma, it inserts 3 commas. I really would have expected the NEW iPad to preform better than the 2015 version, but that just simply isn’t the case. I have seen where numerous others are having th same problem, so I know it is not just my keyboard. I am getting so tired of all the “apple issues”, constant updates, and bug fixes, that after 10 years I am about to give up on Apple. When I got the Ipad in and opened the box, the first thing that popped up was a “Need to update” message. Seriously??? It just arrived!! That should have been a sign to return it promptly. And dont even get me started on the colossal disaster of the iPhone X that I am now stuck with for 2 years. Does anyone know of a way to fix the wireless keyboard issue?? Or, do i have to wait for Apple to get around to sending out a “bug fix” update?
