Many thanks for commenting. Wish I could help with remote screen magnification. If you do find something, please do comment again and I will obv. add that in above.

Sadly we’ve only tested Teamviewer with JAWS (so far) — which is dropping off in terms of usage — since it costs quite a lot, esp. compared to free native OS offerings e.g. Narrator for Windows, VoiceOver for iOS, TalkBack for Android. Again, please do let me know how you get on if you do try TeamViewer. Thanks.
