Report a problem
Tell the developer of PoE2 Oracle what went wrong, or what you'd like the app to do. You can write in English or Russian.
For a problem, the app's own report window is better: it attaches the app's version, the item's text or a diagnostics report, which is usually what a fix takes. In the app, click Write to the developer in the settings, section Help, or report a problem under the item on the price panel. After a crash the window opens by itself. More about it
