I submitted a support request for these two issues. I have seen that many others have similar issues, so I will share my support request and any possible resolutions here for the community.
Issue 1) Android continuously request app permissions that have been granted (repeatedly.) This is not an isolated issue - the support forums have many posts about this. Here is just one:
I posted the following to my own post about this:
Issue 2) Also, Lastpass is not filling a lot of sites even with autofill enabled. This occurs on almost every site on Android, but also on many sites. (Windows 10 Pro 64-bit Version 20H2) and Chrome, Vivaldi, Firefox, and Internet Explorer. (I refuse to use edge.)
Although I do have an ad blocker plugin (uBlock Origin), this occurs even when I have disabled it and reloaded the page.
LastPass will fill my password, but NOT my username. Every time, I must copy and paste the username. This has been occurring for over a year.
I will update this post with information from support when and as I receive it.
Notice how they haven't even bothered to reply. Shows how much they care about their users.
I've been test driving another product (rhymes with WitBarden) for a couple weeks now and haven't yet run into any of these issues. I'm loving it on my Pixel and my laptop. Works every time. The form fill is incredibly more adept (esp with credit cards and payment forms) than LastPass ever has been.
