HubSpot Loxo Integration: Contacts Not Syncing from HubSpot to Loxo

Why are Contacts not syncing from Hubspot to Loxo?
We are using the Hubspot - Loxo integration. Contacts in Loxo seem to be appearing in Hubspot, but contacts created in Hubspot are not showing up in Loxo. Would anybody know why this is?

Hi @cbert25 and welcome, we are so glad to have you here!
Thanks for asking the HubSpot Community!
I understand that you are using the Hubspot Loxo integration, which is an application that has not been developed by HubSpot.
I can see on the documentation that you shared that it is a two way sync “as long as both buttons are toggled on, this will be a two-way sync.”.
Is it the case for you?
I’d love to put you in touch with some of our Community Members and Top Experts: Hi @josephray119, @johnelmer, @ArtyCele and @JenBergren maybe you and/or your customers use the Loxo integration? If yes, do you have any insights to share with @cbert25, please?
Otherwise, the best next step here @cbert25 would be to contact Loxo (there is a chat option on the page you shared, at the bottom right corner).
Since they developed the integration, they know how it works and they’ll be able to help you.
Have a lovely day and thanks so much!
Best,
Bérangère

I have had the same issue too.
