for the record, I've added the COECOV_TOKEN "secret" to the repo setting to make the uploads work:

@slayoo I went ahead and switched the codecov token to the compdyn/partmc one (from yours) however the upload doesn't appear to be working correctly. It at least attempts to appear under the right location on codecov but says "Unusable report". Did the uploads successfully appear under your account when you originally did this? They were not viewable to me.

Thanks! No, I've just had this info displayed - which I understood as implying that only after merging the upload logic the subsequent PRs will get coverage feedback:
