I just broke my product page because of the code residue when uninstalling

The app did not work on our development store, and the app support said development stores are not supported. This is the only way we can test apps without affecting or breaking our main store and for an app that's supposed to be free it's really baffling that this is not supported.

Worst support I have ever received from an app provider. Legit told me there was an app conflicting with theirs so instead of actually providing support to fix the issue they simply told me to go try different apps! When I said I would leave a review, they asked if I would be paying them & told me they were trying their best to assist... they told me to go elsewhere! Support is an absolute joke completely unhelpful so I'm unsure why they have support. App itself would be good if they fixed what should have been easy for them to fix. Never have I ran into app support that couldn't fix an issue with their own app within a few days, let alone what they called tech support. Regardless of if the app is free or not, scary they have 7 apps in the store all free. Support asked me some odd questions which had me question why they were asking, they avoided answering why they were asking & instead said nevermind. Like which shopify plan I was on, not sure how that had anything to do with fixing their app. They asked for access to my store which I granted only to turn around and tell me they couldn't do anything to fix it. So like why ask for access? I got bad vibes & immediately revoked access as soon as he said they couldn't do anything. I noticed 3 IP logins within the several minutes they had access, it was super weird considering they couldn't do anything. Update> Support emailed me personally asking me to delete my 1 star review after without telling me about revoking the API access to the app I assume because I left this review. I was like surely not so I reinstalled the app, they revoked the API again. Of course support didn't mention this in their email, they instead told me they were working on making the app compatible with my theme. Uhha, I don't believe it. I don't trust these guys at all now, I don't like how they have handled this situation & I would strongly suggest avoiding this app & the other 6 from these guys in the app store based on my experience with their support.
