Not an answer per se but what app problems are you experiencing?
And I have no doubt that you are experiencing such problems.
In the general rush towards home security cameras many companies are simply pushing out whatever hardware and software they can as fast as they can.
Little or no testing and/or poorly written end-user documentation with respect to installation, configuration, and use.
Often proprietary as well. And all want to be the "One ring to rule them all".
Doubt that all of the issues/problems are "resolvable" but add some details to your post.
Some specific problems may be addressable. TBD.
Otherwise consider, if possible, returning the system and buying another product set.
