It may be annoying but it is also useful in the manner that it is quicker to use xtals when unloading. This does only apply when you've got xtals in the first place though.
It's still broken PandaGeorge. I've been having the same trouble. Devs are aware of it and are looking into it...hopefully soon.
I accidentally used a xstal and sent a ticket they said next update they'll make a way to disable it.
Yeah, the xtal popup can now be turned off in settings (turn off the Oracle popups). They fixed this several weeks ago.
This really should be fixed. Please check the App Store or Google Play Store for an update and if the disable function still does not work write in to support and let us know!
