XERO SYNC by BOLD

[URGENT] Please help with issue! (There were errors with your settings:
Tax overrides)

Cannot contact developer, 1 Star Review as NO SUPPORT!

Shopify integration has stopped working, we are unsure as to why stopped or how to fix?

I cannot upload screen shots and your app should have a support section not rely on this website contact us box.

Cannot contact developer.

Throws an error and flat out doesn't export orders if the customer name already exists in Xero... Isn't that a pretty basic flaw? We have to manually add orders regularly.

Why we have to pay for this amateurish app with no alternative options and Shopify don't make their own I've never understood.

Are you guys aware of how completely broken the Bold - Xero integration is?? I've had ongoing issues since late June!! I'm seeing a number of negative reviews cropping up on the App site so realise I'm not alone in having problems.
I know this is now a third party issue (Bold) but many of your users must rely on this APP and as it was yours originally, this reflects badly on Shopify too.
We are facing a VAT return in the next few weeks and I have no idea of our liabilities because the Xero App has been so unreliable. This is not a small problem, it creates a massive logistical headache, how do we know what is correctly synced and what isn't. How do we handle the huge amount of work involved in correcting the problems?
This integration is absolutely fundamental in making the use of Shopify viable for us and I'm sure many other merchants. We are a multi million pound business shipping 500 orders per week. This is not a trivial matter and yet the months of delays seem to imply that Bold are not taking this seriously enough!

Bold has made it VERY clear that they don't actually support this app or offer any service for it. As others have mentioned, this app is not compatible with the current version of Safari and Bold has absolutely no plans to fix that (and they will simply string you along with shockingly terrible customer service if you dare to ask). At this point, Xero should permanently ban Bold from having access to their API.

This app is a disgrace. Cannot export anything today. Fails everytime with zero support from Bold. SHOPIFY you need to address this asap as I will be leaving otherwise. The app has been a disaster since Bold took it. And that's putting the ludicrous pricing to one side. Undermines the Shopify product.
