Thunderbird has improved a lot in recent years and I’ve been using it without problems

Thunderbird has a calendar by default now.

Don’t they have to prove it with a photograph? In GermanyI’d laugh in theirface withput a photograph as evidence.

I just checked how it is for me to be sure. My Streetcomplete changes show up immediately on openstreetmap.org/edit.

As far as I know the edits are applied immediately in the backend, however the rendering of the changes can take some days.
