Since I upgraded to 8.90.007 from 8.2.5 (Generic), TVheadend hasn't been able to download guide data from my IPTV provider. It worked fine on 8.2.5.
The URL (as it appears in settings.xml is
http://my-provider.tv:2095/xmltv.php?amp;username=my-usernamee&password=my-password&type=m3u_plus&output=ts
The addon adds the "amp" following each "&", when the settings are saved.
In the log, I see
2018-11-21 16:05:52.000 [ INFO] xmltv: /storage/.kodi/addons/service.tvheadend42/bin/tv_grab_file: grab /storage/.kodi/addons/service.tvheadend42/bin/tv_grab_file

The username and password are correct, since they were working before I upgraded, and the URL works when pasted into a browser.
Is this a bug, or am I doing something wrong? Any help would be much appreciated.
