3D FlipBook - i need Custom work

Hi guys Greeting for your day... I have purchased the 3D FlipBook plugin for a few years and I've integrated it into my website as HTML not PDF with few customization, it works but I have many issues that can't be solved through the solutions you sent to me, So i'm looking for custom work by your side to fix the below issues. a) Images are not shown in some devices like Vivo, and Huawei devices. b) Not works and keeps loading forever in Microsoft Edge (Windows 10). c) Images are missing on iPhone and require a tab on the missing icon to be shown. c) Zoom in /out & full screen, reload the pages and most of the time ti keep loading forever.

Please check and inform me on how to contact you to clarify those issues and make a deal. Thanks and best regards
