Anchor links in message composer(Drag and Drop Editor) do not work with some clients.

https://help.goacoustic.com/hc/en-us/articles/360043097374-Add-and-edit-links-in-your-email#a4

When I contacted the support case, I got the answer from Acoustic support the following:

Anchor link feature is now supported for email clients:

✅ GMail in browser (desktop)

✅ GMail app Android

✅ Outlook Desktop Windows

✅ Outlook Desktop Mac

✅ Outlook 365 in the browser

✅ Yahoo Mail app Android.

Those email clients don't support this feature (and it wasn't supported earlier)

❌ GMail iOS

❌ Samsung Mail Android

Also they mentioned that -

(Android - Web Gmail

iPhone WebGmail

iPhone Gmail app

iPad Gmail app).

It might be a future enhancement.
