No Auto Default Address Swap

This app is trying to solve for an obvious product bug (online comments about it date back to 2015 so shopify is obviously not interesting in fixing it). However, while it seemed to work for a while, it has not been switching the address back consistently for a while and exhibits significant latency so that if a customer submits multiple drop ship orders before the app runs it's process then the default address is lost and it starts switching it back to other shipping addresses. Am reinstalling it to see if that helps- not quite ready to give up yet because there aren't any other solutions available. The developer did reply to me saying that latency is impacted at times by shopify not posting the data to the API consistently- and it could be up to an hour between batches, but that the expectation is seconds, which is what we observed early on. So perhaps it's a shopify issue and not an app issue. When it was working in the beginning it was 4 stars. The lack of a 5th star was just because it can't actually prevent the default from changing- it has to change, then the app switches it back to the previous address. Now it's 3 stars because it just isn't delivering a consistent solution, perhaps no fault of the developer and more likely as a result of a shopify system limitation.

Our customers were having trouble placing orders because the default address on thier account was defaulting to the last address they entered (usually thier customers address). The app does just the job by making sure our customers feault address is always showing when they come to place orders.

super easy to set up and solves the problem immediately. Thanks for the one-off payment option too. Brilliant.
