It used to work on my smartphone, but now it doesn’t work

Hello. Thank you very much for your time.
Please note that this is a translation.
I have been using this plugin for a long time and it used to work on my phone, but as soon as the version was upgraded to 2.0, it stopped working.
Specifically, on a PC, you can drag and drop at the “<>” icon, but on a smartphone, the “<>” icon does not appear, and it does not move even if you pull it down or press and hold it.
Will this be improved in the future?
I look forward to your reply.
