Yes, I've been getting this for a few weeks now. I haven't had time to contact support about it -- largely because my work takes 10 times longer while I watch Airtable spin "Saving..." and "Reconnecting..."
It happens often, but randomly -- so I don't think the size or complexity of my base suddenly reached some threshold. Sometimes activities in the same table will be instant, and sometimes I'm waiting 30-60 seconds for Airtable to catch up. Often it's faster to just reload the page, and when I do this I find my changes saved.
It's happening on different browsers, and regardless of changes to my DNS settings. (Was using encrypted DNS, but changing back to defaults didn't make a difference.)
