Ability to remove history and logs files from iOs devices

When Zwift app crash or can not send activity data to servers, there is a possibility to attach localy stored files to email and send them from the iOs device. My stored data are about 200MB and such a big email exceed my maibox limits. I can remove files by UNINSTALING Zwift app and deleting all app data, but this very stupid resolution. I will lose all statistics and records on this device, and need to transfer GIBAS of data for reinstaling Zwift app.

PLEASE: we need button to remove all stored localy fit and log files.
