Card Database Text out of Date
The card database feature of the Companion app Oracle feature does not work. Rather than displaying the up to date Oracle text of the card, it displays the most recent printed text. As many cards have had errata to update their Oracle text that have not yet had printings with the new text, this makes the feature almost entirely useless. This is made more egregious by the fact that the Gatherer website on mobile advises that Gatherer works better in the Companion app, which is factually untrue.

There are SOME with Oracle and not just most recent print, but too many cards ARE out of date to use this app for Oracle confirmation.
