Yes, exactly, and exactly THIS makes it much more complicated compared to the “old version”, especially for inexperienced users who simply needed copy&paste so far.
Couldn’t you offer both - CSV AND the previous proven HTML table?
I have just tried it again: The way via de CSV import requires a whole series of intermediate steps and queries if the default settings do not fit, with which normal users are certainly overwhelmed.
And even then you end up with a separate Excel table, which must then be additionally imported into the roadbook table, which also requires Excel knowledge, while this was not necessary in the old version where you immediately had the finished roadbook.
Therefore, it remains unfortunately that with THIS version the Excel roadbook can practically no longer be used.
