Pixly .anim Import gone?

I was happy when I read that support for import/export of Pixly .anim Files was added in 1.1.6 to Aseprite. However I couldn’t found that option in Aseprite 1.2.25. Has this feature been silently removed? Which version is the last one that supported that? Will it come back?

It’s actually pretty sad that there is no option to get Aseprite connected with any iOS or Android workflow since there are no compatible import/export options (besides non-layered .png)

hi, there. yes, it was removed years ago:
