Since Friday I have received a “Reference of object which could not be resurrected Task/mgFwimYXjUv” on my iMac, MacBook Pro and iPhone. The iPad still seems to work, however.
I have tried rebooting, starting up with shift, replacing the app, etc. I have written Omnifocus (it happened after hours Friday) and I am sure they will get back to me Monday but I have found a dearth of information on this. The post from October 18 did not make sense to me.
