One of the members in one of my groups asked me about this yesterday. Starting yesterday morning, from another Groups.io group he belongs to, he began to receive multiple copies of the same daily digest. He's gotten about twelve copies of the identical digest, all with the same date/time stamp- August 4th at 6:06am EDST. The latest one he received -- still time stamped 6:06am -- was last night at 8:59pm EDST. He asked me if I had heard about this problem, was it a Groups.io issue? I told him I had never heard of this problem and an archive search of this group didn't produce anything relevant.
Is this likely to be a problem with his email provider? He uses Network Solutions.
