Hello everyone, I have recently purchased an educational course from a website (www.onlinearivupro.com) . The thing is even though I have purchased the course , the website doesn't provide downloading of content to locally or even for offline access within the websites library. I have already paid all my pocket money into this course ,having exams in 2 months ,hoping I could learn from it with full accessibility to the content. I need that content locally because internet connectivity is not stable here and my isp fluctuates a lot,and the course duration is only 30 days ,having to finish all that within 30 days is a lot difficult task.

I tried using web developer console on Firefox , and their is a drm present I couldn't bypass and download it.

Their is an Android app present which facilitates for offline view , meaning once the video is downloaded, internet is required to start the app and then that video can be played while offline. So I downloaded one video for offline view wihin app and I checked the path/directory for the app (Android /data/.comarivupro) and their is this folder containing 2 mp4 files (possibly audio/video ) of the video I have downloaded,and a banner jpj.image and tst.file. When I tried opening the both mp4 files using vlc Android they didn't open at all.

When I checked other files within app directory I found WidevineCencheader.proto Possibly suggesting use of drm.

Also the app detects use of vpns,proxies, and stable internet connection is required. To make things worse ,my old laptop runs windows 8.1 and app doesn't support older chrome versions like chrome 109 which is last supporting version on my pc.

I have been stressed about my exams and completion of syllabus , I request anyone with expertise to please help me with this ,any sort of help/advice is much appreciated.
I completely respect the platform’s policies on content protection, and I’m not trying to break any rules. I just need a way to reliably access the material I paid for, given my unstable internet. If anyone has any ideas or advice please share.
