I've logged a call with Support. But the error message is driving me insane. Getting it daily. I was looking at replacing a Excel spreadsheet with Smartsheet, but if I'm unable to save it the 'smart' sheet is not going to be any use to me. The register I've created has 89,000 cells, which will grow as I'm planning to use it as a continuous improvement register. I see other users have had the same issue, but no one seems to confirm that the reoccurring error has been fixed.
I've tried clearing caches, different browsers. Even removing 'completed' items to make it smaller, still the same issue.
I would really like to use Smartsheet as I like the features it has that excel hasn't (workflows), but the non-saving is a show-stopper for us.
Please help.
