I left my Aeropress unused in my drawers for years for that reason, until some smart people worked out a technique that turns it into a highly effective immersion brewer. Check this technique out https://coffeeadastra.com/2021/09/07/reaching-fuller-flavor-...
The gist of it is:
1. Grind finer (like, nearly espresso fine)
2. Steep for much much longer (like 10 minutes)
3. Don’t press too hard
(3) is generally applicable advice and may already improve your current results. Pressing too hard results in channeling and uneven extraction.
Of course, goes without saying, use good coffee and an appropriate grinder.
