I’m still not seeing duplicates, two fills after I restored the version.
I also haven’t seen a new transaction in that time, which corresponds to the Hello Money email.
So, my Transactions sheet is unchanged during that time.
Balance History:
I had the issue this morning, but thank goodness a restore and re-fill worked. Thanks Heather!
Phew! good news 
I think the push last night fixed it but unfortunately it does require that restore step to get the fix. Ugh such a mess.
My sheet is still completely broken. I now show over $3 million in uncategorized transactions, and I can’t go restore the previous version because it’s stuck permanently stuck in the last portion of “syncing offline changes.”
I restored access to the sheet by disabling offline sync at the document as well as drive-wide level, then refreshing several times to get through freezes in the version history (I think the sheet size may be an issue, so perhaps I’ll take the advice of other tiller users to create a new sheet every year)
However, running the sync again today, I still get a bunch of junk transactions filled in
re-ran the sync, and now I just have a little over $1 million in uncategorized transactions. 3532 updates filled is nowhere near normal, and now I have $1.6 million in uncategorized transactions. So, still not resolved.
Did you restore to a version BEFORE Jan 21 12:41PM EST @shineyspikeything - this specific timing is VERY important to the restore workflow.
