At first I thought it was because of the reCaptcha V3.
But I’ve removed the entire CF7 plugin, reinstalled it.
Sending mail/the form from my desktop, not a problem.
Sending mail/the form from any mobile (android or IOS) doesn’t work.
Beneath the form there’s a row or loading symbols that just keep loading. It never stops, never gives an error or succeeds.
However, if I remember correctly. This theme only allows for CF7 to be used.
I’ve been looking for days now, but I cannot find a working solution or matching answer to this problem.
