Sync Chain in iOS App will randomly disconnect

I’ve been using Brave for iOS for a few months now and like it for the most part. One issue that’s been annoying me is the app will randomly disconnect me from sync chain.

Both my desktop and laptop are connected to this chain and it’s nice for everything to sync together. It seems like every other week the chain will break and I have to add my phone to the chain again. This only happens with the iOS mobile app, not with my desktop or laptop.
