@AAMfP Logged in via my smartphone and a webview-based browser and saw that I can now reissue the #smime certificate in the #posteo webinterface for free. Great! Re-downloading the files failed again because the browser seems to have trouble with #blobs. Then logged in via Firefox on my smartphone but there is no option to reissue — at this time at least. I'm probably clumsy and impatient but it still feels like a #shitshow.
