Thank you for your great email service. However, I've faced severe challenges with your customer support's unresponsiveness (I've sent several emails in the last few months. With no answer to any), regarding the Linux AppImage issues. It's concerning that I've only received responses when leaving public comments (that's why I'm leaving this comment here). Please prioritize addressing this issue. Your prompt attention is appreciated.

@luvcie Hi there, please let us know the exact error you are experiencing with the AppImage and we can bump this w/ our support team. Have you also tried the Flatpak version?

hi, I sent multiple emails to hello@tutao.de where I explain everything in detail. ATM I'm handling the update bug with a helper script I created that I run every time the app disappears, not ideal.
I checked the download page on the official website and Github releases, version 229.240514.1 (Desktop), I don't see any Flatpak package. The version on FlatHub it's experimental and unverified, I prefer to stick with official and verified versions.
Please check my emails, it's all there
