Watchtower Android App crashing on startup

Hi there, I have an Aukey CCTV system and had been using the WAtchtower app on my iphone. I recently moved to Android (samsung galaxy Android v10) and the watchtower app crashes as soon as it tries to open.

I emailed Aukey Support and they replied saying they wouldnt help because i purchased my system in June 2017 and am therefore out of warranty!

Currently i can only view the cameras from a PC rendering the whole system useless as its from my mobile I need access to the cameras when not at home.

Cant view them on a web page from phoen as the app needs a plug in which only IE seems to support.

Anyone else any suggestions on how to get this working or if there is another app I can use?
