Toolbar does not appear at the bottom of a comment when it is only composed of an image. Clicking the comment make the image opens.
The behaviour is not the same when a comment contains text: clicking the comment text make toolbar appears under the comment and i can upvote or downvote or make use of other usefull features.
So the problem is that when swipe gesture is not enable, there is no way for me to upvote or downvote an image comment.
Wow, it actually works. Its hard to get it with the thumb, but once you locate and tap the tiny small dot, bottom and top toolbars appear. Chapeau.
You can tap on the points total or timestamp area as well. Aiming for the dot requires too much effort for me. 😅
