Mine is still screwed up today. It let me edit numbers this morning, but now it's back to the same 'trying to locate' message, and I can't edit comments.
Edited to add:
I found this on Google Help. Many people are complaining about the same thing. Here is one answer I finally figured out how to do it and it really worked....for now anyway.
question:
While updating my spreadsheet, I keep getting "trying to reach google doc" then I can't enter info. It is happening more often and it is really inconvenient
answer:
I've had the same issue - solved by editting your URL address for your specific sheet. Open the sheet, look at the address - then change from
http://..... to a secure address ' add the S ' thus add
HTTPS://..... and you'll find this just works !
Barb: I couldn't figure out how to do that, so I was emailing the whole thing to my son, to explain it to me, and when I put in the URL to my SS, it came up as a clickable link Aha!......so I put the 's' in the url, while it was still in the email, then sent it to myself in order to make the link clickable.
VOILA!!.....Went to my spreadsheet directly from my email, and no more message from Google. I swear!!!
