Does Wave IPTV have a memory leak or bad RAM management?

So I'm trying Wave IPTV on a Nvidia Shield 2019 debloated to get the max amount of RAM I can and unfraternally it comes down to about 770MB free out of the 2GB when I launch Wave IPTV.

I'm also trying it out on a FireTV 4K Max which also has 2GB of RAM and about the same about of free RAM when Wave IPTV is launched.

I'm trying it with a provider which has many groups of channels and some groups may have 200-250 channels and when browsing those groups, sometimes the app becomes very unresponsive and/or slow when loading the contents and the EPG.

I'm also testing IPTV Smarters and I find that IPTV Smarters handles this big groups of channels much better.

Is there anything that can be done to help when caching these bigger groups of channels or a setting to maybe forget other sections when loading bigger groups of channels.

I'm pretty sure the hang up and slowness is because it runs out of RAM, closing the app and restarting it solves the issue usually till it runs out of RAM again it seems.

Also on the latest version 2.0.1 for live TV it seems you can set the different level of buffer in seconds but not for VOD in the settings now that the settings are separated. before it was just one setting.
