I'm deeply sorry having to report one more time a problem.
I just noticed there is something wrong with the writing effect, since update of WordPress 5.2.4. The writing effect in general works. However, prior the text having the writing effect, the tag displays the text once again, but static.
It's no corrupted file. It's in both files w/o me touching these. Thus the only explanation would be the update to 5.2.4, as nothing else has been touched (except for eliminating the Google Web Fonts with the $handle code in functions.php of course).
