Issue with video downloads stopping midway on Android — anyone else facing this?

I’ve been running into a strange issue lately while downloading videos on my Android phone. The downloads start fine but often stop midway without any clear error message. I’ve tried switching networks, clearing cache, and even restarting the device — nothing seems to fix it completely.

I’m using a third-party app that normally works really well. If anyone’s curious, you can visit here — it's the platform I’ve been using for video downloads.

Has anyone else experienced something similar? Could it be a background data restriction or a device setting I’m missing?
