Hi,
Yes. The cron service we offer won't work on another domain name than the one linked to your subscription.
So any feature which needs the cron won't work:
- sending of the emails of the waitlist when you restock
- refresh of the currency rates
- out of stock emails
- mass actions with "every minutes", "every days", "every month" or "every year"
- automatic import of CSV file with the HikaShop products update plugin
- automatic generation of the Google products xml feed file
etc
Now, the shop frontend would still work fine without any of these and if it's for a dev site, you probably don't need these features there anyways.
