Preview errors
Check the required date, amount and type columns. Review every highlighted row issue. Fix malformed quoting or missing fields in the source file, then preview it again.
A plan message
You can preview a file even when your current plan cannot import it. A Premium-required message means the server declined the import; the screen states when nothing was imported.
The connection dropped
The app may not know how far the import got. Some rows may already have been added. Choose Check Activity and compare the records before retrying the whole file.
