I was just browsing the Keyman website to test some keyboards and found that there was a broken link. It seems that wherever the “Help on installing a keyboard” link appears (e.g., https://keyman.com/keyboards/install/sil_euro_latin?bcp47=es), it doesn’t work:
That page also references a “blue Support tab”, which is not available in the mobile (narrower) version of the website. On the desktop (wider) version, the blue Support tab is available.
