Chimahaga review for Shopify Marketplace Connect

Really poor quality customer service. It took months from the time I reported the problem to the investigation, and then they told me to contact shopify myself because the cause was due to the data values provided by shopify. Why don't they try to check with shopify themselves regarding the problem with their app, which is released as an official app on the shopify platform? And the glitch is not a small one, but a fatal one for the users that tracking information is not reflected to Etsy properly. I really can't believe it.
