Paypal zettle app not syncing to shopify?

[Thewateringcan]

We use the PayPal zettle app in our shop and its stopped syncing with shopify (not deducting inventory when we make a sale).  I've tried disconnecting and reconnecting but not working.  Anyone help please or having same issues in last few days?

We are also having this issue and products added to Shopify are not all synching to Zettle - would be interested to know if you managed to get a fix for this.
