[Android Apps and Games] IronTechmonkey:
Pardon a mega-post but I'm combining questions about a few things; 1) A possible glitch with images from android to Chromecast device 2) An odd difference between 2 Chromecast devices, and 3) a conundrum about iptables. Disclaimer, only the first of these might be a bubble glitch or limitation. The others may a bit off topic here but I've found no solutions elsewhere.

The setup: Bubble app on MotoX4 LOS 15 (or other Android devices), accessing Bubble server on Linux Ubuntu, playing video from same android device, or SMB shares on Ubuntu, or Kodi shared library on Ubuntu, to integrated Chromecast on one TV or Chromecast dongle attached to same or other TV.

1) A minor Bubble issue or limitation which has been around for a while. Images do not display when shown from Bubble to Chromecast if Bubble server is detected on network. When server is active only the bubble text shows on the screen indicating that it is connected but no images are shown. When bubble server is stopped then image files play to Chromecast. It's easy enough for me to disable the bubble server in these cases, but is there any other work around?

2) This is not a Bubble issue, but I wonder if anyone else has seen something similar or may know how to tweak it. Comparing integrated Google Chromecast on one TV to a Google Chromecast dongle (attached to same TV or another TV):

With the same media (a library of many various video file types) being played from the same source by the same Android device then:

- On the integrated Chromecast some video files are incorrectly sized; 4*3 video in the correct aspect ratio and seemingly centered on 16*9 TV with black bars on left and right as expected, but video is larger than screen and right side and top of video is cut off. It gets a bit weirder; For clips that are affected as described above: Going forward to them in playlist will induce the symptom but going back to them from the next video in the playlist will often cause them to reset and resize properly on the screen.

- On the Chromecast dongle attached to either of 2 TVs one of which is the one described above the videos plays okay,

This seems like an issue between the TV and its own integrated Chromecast, l but I'm wondering if anyone else has seen something similar.

3) This is definitely not a Bubble issue, But maybe there's some advice out there about how to un-bork my network access to the bubble server. After installing and removing a firewall management app on Ubuntu where Bubble server runs, in spite of being careful not to make permanent changes, there has since been no access to the Bubble server (or the Kodi library). Firewall apps and command line all indicate firewall is not even running or is inactive and the Android can properly access SMB shares on the Ubuntu computer. When IP table rules are flushed on the Ubuntu computer then Bubble android can see the Bubble server (but then other bad things on for the Ubuntu computer until reboot).

Kodi's lack of password protected access to the library from other devices on the network makes it easy to abandon but I do want to access the Bubble server from Android devices, so I'm off to research ports and services. Again, if anyone's heard of something like this, I'm all ears.

Apologies for taking it a bit off-topic. Until I scrambled iptables. I was happy as could be using Bubble to cast and should have never clicked install on that firewall program.
