First of all, to other people here on the forum, please don't turn this into another thread where people discuss Aurora.
Nibble0289 I've heard that Aurora store isn't adviced before, but why is that.
Here's a quote from the project account on why that is:
Whether people have a high threat model or not, we recommend using the sandboxed Play Store rather than Aurora Store for installing apps from the Play Store. Play Store itself is much more secure and avoids the compatibility issues of Aurora Store. Aurora Store doesn't provide Play Asset Delivery or Play Feature Delivery along with installing the wrong variants of apps by default.

The post is from over a year ago, so I think the part about installing wrong variants by default is no longer the case, but it was then. Basically, there are both security and app compatibility concerns. There are a lot of discussions about Aurora here on the forum. If you're still curious about it you can find one by searching. The topic is a bit controversial.
Nibble0289 Should I use it for this instance or no?
I'd say that's up to you. Like I said earlier, it's better than other options if installing from Google Play isn't an option. It's unfortunate that Google is doing things this way. There's no real good reason for them to be blocking apps from being listed on GrapheneOS under the guise of "security".
