Some customers are having download issues. The app doesn't send the download correctly and I have to send to customers manually.
EDITED ON February 15th, 2021 :
The issue described here was due to the fact that your customers downloaded the files through Instagram stories and with a very basic browser that didn't support the downloads. Despite that, I found a workaround and the issue is now fixed.
ORIGINAL ANSWER BELOW :
As I explained in our email conversation, this issue was due to the fact that your customers are accessing your website through Instagram stories. The browser on Instagram is a very simplified one with limited features that does not properly support downloads. But still, I have found a workaround for this point and it is part of v2.7.2 published today for the app. My number one priority being customer satisfaction, I really hope this fix will change your mind on this review!
