First of all: Thanks for your great software! When I use the Data Manager to download data. I use Alphantage and the symbol STMN.SWI. The title is found via "Check". But when I click OK, I get a Message with "Invalid Data". The whole import function seems to work quite at random. Sometimes it does, and sometimes it doesn't. What can I do? Should I get an IEX API key too? Thanks, Elli
