I did explore this before, but if you already have Redstor before you join LGfL you are not allowed it for free.

We use https://transparent-uk.com/ It's based on pupil numbers, with set tier pricing. It's unlimited storage. One of my infant schools pays around £400 per year, whereas my biggest school pays around £2500

I recommend the Redstor EDU bundle, been using it for three years now, and the renewals only seem to go up by about £30 a year.

Chromeflex?

+1 for Medhurst

Yes, so in the iPadOS 27 patch notes it says they've changed something with how pins work, so I'm thinking on the ViewSonic AirPlay settings, could you try turning off the pin as a test to see if it now works.

Just looking at what they've changed in Ipad os 27 are you using PINs or anything like that for AirPlay? Maybe try turning off pins and see if that works.

Surely ViewSonic support is the way to go.

An easier option might be to restore said iPads to 26.6 and block iPadOS 27 through your MDM for now. *EDIT just found out that 26 is not signed anymore

I know it doesn't solve your exact problem, but a workaround would be to use the AirServer app on a PC

Just remember: buy cheap, buy twice. You might as well just buy the UniFi equipment and know what you're getting. Nothing wrong with Yealink phones, though.

We're using Intune, and it seems okay on my test build.
