Describe the issue

Hello dear HACS Community, I have a problem with Fully Kiosk browser and Hacs integration.

I really like using Hacs because I can always find new great components and integrations. It also all works very well when I use a browser on my computer (Chrome) or Safari.

Now I want to use HomeAssistant in the Fully Kiosk browser to use a tablet on the wall with Home Assistant. However, in doing so, I can’t use the HACS components because they are suddenly not found.

Also the HACS icon in the control bar on the left side is no longer displayed and I can’t access the HACS integrations page in home assistant itself.

When I now open a Home Assistant LoveLace page, the following error message appears instead of the HACS components:

Reproduction steps

1. launching the Fully Kiosk browser
2. call a page in Lovelace with HACS integration
3. see faulty integration …

I have found out, that this is regarding webviewer on the device. Amazone Fire Tabs are using an old version of webviewer which might not be supported by most of the custom components. I decided to change the tablet. Thanks for you help.

If the supervisor is not showing, then HACS would never work, they are built the same (mostly) You should use an other browser if that one is so outdated that this is not even working.
