interaction between cf7db and the smtp-mail-features

Hello dear all, good day dear cv7db-developer and user.

first of all ; i have to admit and confess: this is just a outstanding plugin it rocks.
i really love this awesome plugin the great cf7db-plugin for its versatile features.

now i have several little questions:
I instead installed WP Mail SMTP because i love this plugin – see https://de.www.ads-software.com/plugins/wp-mail-smtp/

i also want to install the contact-mailer CF 7 – see https://www.ads-software.com/plugins/contact-form-7/

and i want to install the cf7db plugin:

But i have heard that this plugin could (!) immediately interrupt the operation of CF7 which instead already worked well. https://www.ads-software.com/support/topic/wp-mail-smtp-breaks-contact-form-7/

question: did any body encounter such issues:

Did anybody have similar problems? am I wrong about configuring WP Mail SMTP?

love to hear from you

regards
