Ipad obsidian problem

Since the last update of obsidian on ipad these lines appear when I bullet point each line
Also I can’t move to the line I want by touching where I want to rewrite something. I have to use the arrows on the mobile toolbar to go right and left one letter at a time. If I use the up and down arrows it automatically jump to a specific line and can’t move from there except by the left and right arrows.
This only happens when these vertical lines appear.

Another problem is I can’t open pdfs in obsidian.

I wish obsidian on ipad was alot more efficient.
I have more problems but one at a time
Sorry if I repeat myself. English isn’t my first language
