Lovelace and Fully Kiosk Browser

Hi, has anyone been able to successfully use FKB with a Lovelace user interface? I’ve got FKB running on two different tablets and on both I can see response delays up to 30 seconds. On my phone I can display the same URL via Chrome and the response is instantaneous.

Any ideas? Thanks.

When I keep the “Agent” to default everything goes well. But have problems with streams then (break after 30 seconds). Change “agent” to a fake one stream (browser_mod) is working but then a big delay with loading of tabs
