There are quite a few different browsers and if you also spread this out on the different OSes and devices, then the number gets quite big.
It will be hard to document all this and it will also have to b kept up to date, so a way of monitoring browser updates and test for changes is needed.
These resources would have to be taken from other projects, so I prefer that the users themself search for the way their particular setup is cleared.
I think the problem is the use of front end instead of browser. A lot of times people don’t make the connection. Clearing your browser’s cache is internet 101.
Until now, when I got that message I just restarted Chrome on my PC and everything seemed fine - so I assumed that was all that was needed.
What if I’m using the HA android app as well? Do I also need to do something on my phone (and I suppose also separately on my tablet)? Or do the apps take care of this automatically?
You either force close & restart the app, or else you go to the app settings (on your phone/tablet, not inside the app itself) and select “Clear Cache”
