Workaround

Hey team, there's an ETA for this issue? I can reproduce this bug on XF 4.8.0.1687 when I use any kind of collection (Collection View or BindableLayout).

Hi folks. ETA on this? It's blocking my stories for a large client who has legal obligations for accessibility.

This PR fixes a lot of fundamental issues with CV/LV/ScrollView on iOS #13300

The core issue with the reproduction on this issues is that TabIndex/TabStop doesn't really work very well on iOS/Android and I'd recommend against it

If you can test the latest version of 5.0 @danhermes and if you're still having issues can you attach a repro

If you take a look at https://github.com/PureWeen/A11YTools you'll see some alternative solutions for TabIndex
