Do not waste your time

$17.00 Adobe .pdf reader. Will not sync iCloud. Locks average multi tab .xls spreadsheets because it cannot translate blank cells where simple data entry is required - like: name, date, interest rate, etc - BASIC info transfers to other tabs. This makes it useless for financials: IRR, NPV, DCF. Their documentation says these functions are supported - but no info on how to resolve issue of locked file. Cannot open / do not pass go / save your $.
