Those of you who are Google Merchant Center / Base merchants should be aware that the scheduled automatic uploads are currently not working.
Ronald from Google posted a thread at the Google Merchant Center Help area saying:
We've noticed that a few users have reported that the scheduled uploads feature is not working since the last few days. Our engineers are aware of this issue and working to resolve it. In the meantime, please upload your data feeds manually. We will update this thread once this issue is resolved.
This is not the first time, it happened a few months back as well.
There is no estimated time for a fix, but I suspect it will be resolved within 48 hours.
