In my current template that is based on an APA 6 manuscript (Link to the template) the [!h] function doesn't work. It keeps putting images on seperate pages at the bottom of the manuscript.
(tried all variants of [!htbp], etc)
Hopefully someone is able to help!
As documented in the apa6 manual, by defaults floats will go to the end of the manuscript as required by their publication systems, you can use the floatsintext option to give normal latex behaviour.
Note however in the normal latex float positioning you should normally avoid [!h] as it is very restrictive and gives latex very few options to place the float. (It will usually give a warning and change this to [!ht])
[!h]is quite, shall we say, underpowered. It will do its best to place the figure there, but aesthetic concerns will quickly beat it and if TeX can't find a good way of placing your figure there, it won't place it there.

A common misconception. – Johannes_B Oct 28 '16 at 15:15[!h]is that it prevents latex placing the float at top or bottom of a page or on a float page, so it leaves latex little choice but to float to the end of the document that's why it gives a warning and is changed to [ht] in most cases (but that is still restrictive) – David Carlisle Oct 28 '16 at 15:50
