Indoor Home SE a waste of money with these issues or does anyone have an actual solution?

I hate these cameras so far. Sooo many people have the same issues as me - maybe someone has a solution, because roku sucks for customer service and gives the same response to everyone "we'll forward it to our proper team." Sick of companies.
First off, the cameras work great the 1st few days of the 14 day trial version. Then they both started messing up to where video playback within their app lags almost like it plays in frames but the seconds lag too, but if I download the video...its fine. Then after a bit, it shows there are like 14 sec videos but only gives a blurred snapshot and "failed to load". Its a joke. I figured out that when it starts doing that, you need to go to each camera and click to restart camera and then it will start recording video again (but still lags in playback view). I want to view the video within the app and watch it play smoothly and Roku doesn't do it. I use Samsung Galaxy 9+. My camera is also only 6 ft from my wifi gateway. Also...the speakers suck. The volume is extremely low and nobody can hear you talk to them if they are at your camera unless they put their ear to the camera - everyone is complaining about it too. When someone walks and your camera records, it blurs features, so good luck trying to identify faces because you won't be able to if they are moving - their bit frame sucks. What's really irritating is they have HD on LIVE viewing, but you WON'T have HD for a recorded video (figure that one out) - it's like they reduce the quality to save space. I then went and purchased their $10/mo subscription which covers all cameras because I wanted to see if having the subscription would unlock some features I thought existed and maybe playback would be fixed and the quality - ummm no. You get no extra features. What a joke. The only thing you get from the subscription is just being allowed to get your usual **bleep** videos instead of just snapshots that you'll only get when the free trial runs out on your cameras. Their software is unstable with recording quality and playback smoothness, and It's just a matter of time before I'll have to reboot the cameras once again because it decides to only do snapshots. I'm new to security cameras, so cloud is basically their app? So if I can watch recordings within the app, that's their cloud? Because my Samsung cloud doesn't have Roku recordings sent to it.

Any help  in resolving my issues..would be soooo appreciated
