Dropbox integration

Hello,

I am using a paid subscription to acrobat on an android tablet (android 13). When importing à file from Dropbox it opens, can be annotaed and saves on the same file directory on Dropbox. However,  when Ido the same but modify the pdf, the document is said to be saved but I do not know where,  except it is not in Dropbox. Is possible to have the document saved in the same folder it was on Dropbox ?

Kind regards.
