Add Bulk contact through csv is not working

[dmg]

I am trying to upload bulk contact using csv file, but it is not accepting it.

It shows the above error that it is not a valid csv file.
I tried uploading the sample given, for that also it is giving the same error.
Kindly guide how to upload the bulk contacts.
I can not attach that csv file here also as that format is not accepted.


Best Regards,

Kindly reply this is urgent.
I can not send message to my registered participants without uploading their contact.
If this feature is not ready then tell me the alternative method to upload my contact data.
I was using Pabbly Connect for the last one year and was highly impressed by the support for that product, but it seems proper tutorial videos, documents and support team is not ready for ChatFlow.
