Hey there!
Could you tell me what version of Thunder you’re using and the instance you’re using? Additionally, does this happen to all images or only a few images on the feed?
If it only happens to a few images on the feed, I would try to increase the time Thunder tries to determine the image dimension size. Here is a quick link to that setting: Thunder Setting: Debug > Feed > Image Dimension Timeout
Hey there!
This issue was noted and is already fixed in a nightly TestFlight build. See this GitHub issue for more details.
If you’re not on the TestFlight build, there is still a workaround for this issue by setting Thunder to portrait mode temporarily. Doing this should bring back the back button on the top left!
