Grimoire&Alchemy review for Seal Subscriptions App

This app has been nothing but a headache since day one, even paying for the highest tier. Half of my subscriptions don't go through (customer support blames shopify, shopify blames the app)- the only fix is to cancel the current order and send a new subscription link to every customer this effects every month (they do advertise some thing you can pay for to 'help the payments go through- I shouldn't have to pay for another thing to fix the issues that should exist in the first place for an app I already pay for). It is extremely hard to use and confusing- the way things are worded are not user-friendly. There are only a few help videos online, which I did use, but there are no help videos for many of the issues I have come across. It's very hard to get in contact with support since they are in a different time zone, especially for time-sensitive issues that arise right before/at renewal time- if you're in the states, expect about 24 hours between each response- I usually email with the issue, a day later get a response asking questions, reply answering the questions, a day later get another response with more questions or possible fixes, reply that the fixes did not work, another day for another response, so one issue that should be resolved within a few minutes takes 3-7 days. Automations don't work properly- I just had over 250 subscriptions renew to the wrong product because the automation didn't go through, even though it shows fine on my end. The app uncancels and unskips randomly, and charges people when they have already cancelled, which means a lot of angry emails. Unfortunately, I will be moving to another app, because I am losing so much time to answer customer service emails and fix issues, and losing income because so many customers who no longer trust me because every renewal there are huge issues and I seem unorganized and confused (which I am). The one good thing is customer service is always friendly, even if they can't usually help or fix my issues.
