Thanks a lot for your help!

hey @npracht happy to test, but I cant provide my customer's actual hubspot API creds. Is there a test instance?

p.s. ive replaced my own sandbox instance with the new test HubspotIntegration.php and MySQL is still throwing errors - Hubspot is providing a millisecond timestamp - SQL isnt quite liking it - Logs:

This issue is not fixing date/time field. Please unmap this field for the test and just try to sync. multiselect field (this is what is supposed to be fixed by this PR).

[brendansmallco]

Thanks @npracht - unmapped the field, synced and it appears to be working. Multiselect field is coming through.

If you have any hints for me about where the code for timestamp handling is that would be handy!
