I am attempting to upload a .ipa for an update of an iOS phone app we have developed, it's a really plain vanilla app, no watch or share extensions or anything like that.I've recently switched to using Transporter to upload apps, as I've generally found this more stable than using XCode (used to use Application Loader, but that's obsolete). This morning when trying to upload the app, it failed with the error message:> Unable to process validateMetadata request at this time due to a general error (1019)I suspect that this is just a temporary outage on the AppStore webservices side, but couldn't find anything in the forums specifically about this issue.For the record, the complete delivery log from Transporter is:[2020-04-08 09:45:53 AEST] INFO: Configuring logging...
