[2021] Mobile has fully launched, yet I still cannot download the game on my Android tablet

I bought this tablet 2 years ago for $250 in hopes that I would be able to play RuneScape on it. At the time, I still couldn’t download the game on it, but I figured since it’s still in beta that’s understandable. Well, yesterday the game has fully released and I STILL cannot download or play RS3 on my tablet. I just don’t understand. I’m hearing everywhere people are playing them on iPads, and even people with substantially less specced out Android tablets are being allowed to download and play. I really don’t understand. This is a Samsung Galaxy Tab A 10.1., still by no means a relatively old tablet. I’ve heard nothing but radio silence from Jagex on this every single time I’ve asked over the years, I’m honestly ready to just sell it for an iPad.

Just wanted to vent a little, maybe I can get some of your experiences with mobile? Do you think trading for an ipad is worth it or should I just wait it out?
