There remains a major bug in the import and export of dates to Google Sheets which causes serious data corruption. I reported this to the developer a year ago.
a) If one can set the date format for Import/Export to yyyyMMdd via the settings
b) This exports a Date field (not a time date field) in the format 20181019 (which is good)
c) However it does not work on import;
If one changes any data at all in the google sheet (apart from the date) it sends the correctly formatted date back to memento as 1 January 1970
not only making it impossible to edit the google sheet, but also causing massive data corruption and data loss (very bad....)
It would be great if this could be fixed, because using Google Data Studio from memento is stupendous. How does one get the attention of the developer here, even for critical bugs that are product killers?
