I'm finished with using 4.8.1, for now.
Here are my complaints (PITA = Pain In The A$$):
1. Sticky posts do not show up (yes, I know this is being addressed).
2. HTML mode: I click in title bar, type a character, then the cursor goes all the way to the end of the title bar. PITA
3. HTML mode: when I switch from Visual editing to HTML, and tap in the post composing box, automatically the cursor goes all the way to the bottom. of the box. PITA, especially for long posts.
4. HTML & Visual mode: There needs to be more lines of textt in the box. There are only 10 lines.15 (at least in v. 4.5)
5. VISUAL mode: when I switch back from HTML to Visual mode, all of the line breaks and spacing all appears to be removed, and appears as one big long paragraph. HOWEVER, when switch back to HTML, line breaks are there. I'd rather have the visual mode at least show the line breaks correctly.
I think this is all.
I've found dealing with all these issues in 4.8.1 just too much for me. I've re-installed v 4.5 on my iPhone (yes, I save every version of every app, in case something like this happens). It's just too difficult to work smoothly with 4.8.1, for me, at least.
When these issues are fixed, I may try the updated version. For now, I'll stick to 4.5.
