Guys i SOLVED the device latency issue!
It appears that the latency comes from the quick controls automations section inside your devices. If you used to make automations through them, then loading when opening a device which inludes quick automations gets worse, the more you add. You can solve this by going to automations, scroll to the bottom tap the 3 dots at the top right, tap delete, select all the quick control automations and delete them. Close the app, and clear its cache. Open the app and open a device which has quick automations inside. It should be fast to load.
- WARNING !!! Recreate the automations you had setup using the quick controls automations panel BEFORE deleting them!
Old loading time 8-10 seconds. Without quick controls automations setup 1-2 seconds.
Here are some screenshots:
