I’ve added support for PVR multi-instance in v21.1.0 which should go out in the next few days.
Note that only the first portal will have it’s settings migrated, any others will need to configured manually. Note that all the original settings will still be in “addon_data/pvr.stalker/settings.xml”.
With multi-instance it is now possible to run multiple portals at the same time. There are no addon specific settings, all settings are now configuable per instance. The active portal setting has been removed as it is no longer required.
