Each of the Classic SDKs can only be run in one instance at at time. This means that you can only have one instance of the Support SDK and one instance of the Chat SDK running at once.
If you want to change Support or Chat account at runtime, be aware that this is not supported. While it is possible to initialise with one account and initialise again with another one during runtime, we do not support such configuration.
When moving your account to Agent Workspace, be aware that this will slightly change the way attachments behave in Chat SDK. The files received won't be opened directly, but will rather be opened via a browser in order to be downloaded. This doesn't affect images that will still be rendered directly in the Chat UI.
Both Chat SDK and Support SDK can only attach one file at a time when in chat or ticket respectively. It is however possible to attach multiple images directly from the gallery.
The classic Chat and Support SDKs do not support Markdown formatting. Some formatting may work but we do not test nor develop this. If you want to use Markdown formatting in your ticket, be aware that the results may differ between iOS and Android when opened through the Support SDK.
