If you try to confirm an email address from the email you send, all you can read on the landing page is "Click the button below to confirm your account's email" with no visible button. Tested on PC ("Chrome Version 131.0.6778.86 (Official Build) (64-bit)", "Edge Version 131.0.2903.70 (Official build) (64-bit)" under Win11 "Version 24H2 (OS Build 26100.2425)" and Android 14 (SM-A546E Build/UP1A.231005.007) using Chrome 131.0.6778.81).
Same results on all.
If you highlight the "click the button..." text and drag the selection box with the mouse you can see the text on the button and clicking it works, but most users won't think of that ...
