For conditional formatting to work, you have to have a consistent output column or row. "Keep formatting" only works for standard formatting.

I could but I would have to do that after every archive right? I have it paste to the next empty row.

Could you try adding the same conditional formatting in the output column or row?

Hi Rafal,

Triggers are managed by Google, so the most common cause of scheduling issues are Google's limits, specifically that they only allow 6 mins per hour, and 90 mins a day total runtime. These runtimes are shared between all your sheets that use triggers, so if your account is running a lot of triggers, or uses a lot of processing time, triggers may not run. To avoid this issue, I suggest removing any unnecessary archive processes and spreading out your triggers, i.e. instead of scheduling them all to run at midnight, set some at midnight, some at 1am, some at 2am, and so on. You can also navigate to https://script.google.com/home/executions to see if services other than Archive Data are expending your quota.

Looks like a temporary glitch on Google's side. Please refresh your sheet and the full menu should appear.
