i have that issue as well, sometimes it’s missing results and other times i get the same result repeated on page 2. not sure why that happens, but i guess it’s just a bit buggy.
instaloader can scrape instagram accounts. do note that they’ll ban your account if you use it in a ‘suspicious’ way, i.e. downloading multiple times or simultaneously.
you can setup a cron job on your *nix machine and setup a script to notify for new files (posts).
sadly barinsta development stalled over a year ago and in my case I get banned every time I use the app and need to do weird captchas on the official site.
The one I know about1 is the data being sent every 24 hours with a unique ID that they use to count active users. I’m not sure, I mostly do trust they won’t do anything weird with this and use Vivaldi sometimes, I guess it’s up to you to decide if you want to continue using.
Vivaldi is decent IMO but there are some telemetry some might find distracting.
BTW, are you using Windows? What do you mean there’s no easy way to update Ungoogled Chromium?
