Oshinko, same thing is happening to me when opening BVTK or any other ticker on TDA app. I'm able to open the app and check different tabs but as soon as I tap on any ticker to view summary it freezes up. Going to uninstall and reinstall, hopefully that fixes that issue.
Reinstalling wont help. Its an issue with the market data on specific tickers...mine always freezes with sf*r and bvtk. Ive inquired about it before with customer support, if enough people do it they might try to fix it.
