DS-7204 notifications to Android iVMS-4500 (Samsung) not working

Hi Forum,

I have a hikvision 7204 DVR and using the hikconnect and IVMS 4500 android app but the push notifications dont work on my Samsung S10 but do work on my older Samsung S8, ive tried power mgmt settings, updating software on the apps, checked firmware but the notifications still dont work.

Any ideas?

Thanks
