I've now noticed in 3.5.2 some CSS styling is not working as it was before. On 3.5 I was using float:left for some images, but now on 3.5.2 that isn't working. Is this expected?
Sorry for the delay answering your question.
On 3.5.2 we introduced LTR support which makes CSS more specific. We need to add ion-app.app-root as a prefix on all css rules to override default behaviour. So you probably want to use a more particular css rule to enable your properties.
