Today I was experimenting with Read Range (Activities - Read Range), and noticed it wasn’t populating the sheet names in the “Range” dropdown for my spreadsheet provided via Spreadsheet URL. After some testing, I realized that the Range doesn’t check that field. Instead, it’s checking, the Spreadsheet Template (even if it’s blank and never expanded).
Entering my URL into Spreadsheet Template makes the Range drop down populate.
When I manually select the spreadsheet via Browse it works properly. This bug seems to only be present when entering a sheet ID or URL.
