XStore 3.11.1 is compatible with WC 3.0.1 but has out of date files for the latest versions of the WC. We plan to release the new update on the next week. WC plugin releases updates every 2 days. Seems it still does not have stable version. Anyway, what version of XStore theme and WC plugin do you use and what compatibility problems do you have? Or you think that it’s not compatible just because of the notices in the admin panel?
