Hi @antcrescendo
Sorry for the late response.
1. RE: Why my UM buttons suddenly change language the moment I activate the TranslatePress Plugin?
What’s the default language set in your global settings?
2. RE: Also, how do you translate email notifications in UM?
You should be able to switch language when translating email templates in the settings. The WPML switcher is at the top admin bar when viewing the Email settings page. You can also translate the Email via your theme. Please see the doc in the link: https://docs.ultimatemember.com/article/251-using-different-translation-of-html-email-template-files
3. RE: Why is WMPL the only multilingual plugin that offers compatibility features?
UM should work with different translation plugin with the Translation files available on https://translate.www.ads-software.com/projects/wp-plugins/ultimate-member/language-packs/
4. RE: Why is making a user registration form so puzzling?
Please read this doc to get started and understand the UM features:
