I uploaded a bulk vcf file of contacts to ecloud.global but only a subset of the contacts appear in the contact section of the cloud. There were some error messages but these only flashed briefly on the screen and were not readable in detail. Are there some known limitations, e.g. incompatible field names or encodings?
no here is no way, only manually. The upload of contacts and appointments does have serveral issues and you will find here and in bug report some posts regarding upload issues.
Pls search the forum so you will find them.
