Changing phone numbers country code

This is something that Manychat should change, the option to change the default country code, but as usual they don´t care. The only way to change the phone number of a contact is using the app, you have to select the contact and then click to edit the phone number and change the country code that you desire.

It's a pain in the ass in all the senses, you can't use the desktop and can´t define the default country code. I'm searching for an alternative to Manychat and will leave soon if Manychat continues ignoring its costumers.

can u please show me ur real example 

cause i just check and i simply dont even have default +code 

This is an Essential request

Still no update on this?

Im collecting lots of phone through instagram. Customer sends area code + phone number. Example: 21999999999.
When the number is stored in the contact card, manychat adds the “+” to the number. So it goes like +21999999999.

The problem is: this number is incomplete. I need the coutnry code to come first (in my case, +5521999999999).

Without the correct country code, even if i manually correct the contact’s phone number later, the “Whatsapp Opt-in” won’t be available, which means i can’t contact those customers via Whatsapp.
 

This sucks!
