Flatpak: Platform 'org.freedesktop.Platform.openh264' not found
Evince Nigthly Flatpak requires org.freedesktop.Platform.openh264
(branch 2.0) from flathub which is not "updated" (in terminal: Op = u) because it is not found: Warning: Server returned status 404: Not Found
.
However, I have org.freedesktop.Platform.openh264
version 2.1 (branch 2.0) from flathub installed (probably installed with another software in the past).
