The contact info for AISLER if you need support re. the plugin appears to be to mention them on Twitter, or at least there isn’t a different contact method listed in the PCM description.
So, they may also reply here in the forum, but it may not be the fastest way.
as KiCad’s API changes quite frequently we decide to not keep the plugin backwards compatible. If you are using KiCad please download and install this version Release 0.1.9: Add support for KiCad v7.0 · AislerHQ/PushForKiCad · GitHub @craftyjon is there actually a way to provide multiple versions to a plugin? Right now it is necessary to manually install a plugin via ZIP file if the KiCad version requires a previous version of the plugin.
