Hi everyone,
Timo, I’m experiencing the same issue. It appears to affect all my devices (iMac, iPad, and iPhone) and occurs with all invoices—both old and new—when using PDF Layout 2. Modifying the font settings while Layout 2 is selected does not resolve the problem. However, when I switched to Layout 1 in order to send out some urgent invoices, everything displayed correctly without any issues.
I hope this information is helpful in identifying and resolving the problem. Layout 2 is my preferred format, so I’d be glad to see it functioning properly again ;-))
