Is your feature request related to a problem? Please describe.
I want to be able to update appVersion with each app update. Also, it can be a configurable option. appVersion is not updated due to a chance of DDoSing your own server #24

Describe the solution you'd like
I suggest to use a task queue, to reduce a load from updating appVersion directly by calling Installation class.
This, of course, means also updating other SDKs.
