Summary of the issue you are facing:
The best most thorough description I can give, with a screen shot, is a link, so I hope these are allowed: Mastodon thread on mstdn.ca
Since last November, I have been using Nextcloud to share iReal playlists with band members prior to our performances, sometimes during!
Previously, I would get the share link from my mobile Android NC app, paste it into the group chat, as each member clicked it, they would be offered the iReal app, click it, and iReal would then ask if they wished to add this playlist. It worked beautifully, until this morning. So far as I know, the only change was a recent auto-update to 29.0.6.
What happens now is the chat flips to the browser where they see a preview of the source code of the html and a ‘Download’ link. On Linux/Firefox, clicking the link fetches the html file, but on all mobile platforms, the file is renamed as filename.txt and not recognized by iReal.
Steps to replicate it (hint: details matter!):
- generate a share link for a file with extension .html and post to social media
- click the link and you will get a preview page with a download link
- select ‘Download’ and on mobile only you will get a .txt file.
for example: playlist of a few #ireal xmas tunes
(that’s on a homecloud, so please don’t hammer it)

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
