onlyoffice co editing

hi @ all

so i have installed next cloud snap and also installed only office from within the app with the community server, i have added the path for only office https://test/index.php/apps/documentserver_community/ within the only office app disable cert verification .

Now my problem is the co editing it seems that then i create a new lets say excel file and share it so both users co edit ,having everything correct meaning the settings for that when user1 types in the file user 2 dont get any data but for a strange reason it can see where user1 points its mouse with in the file.So no data at all.

is there something else i am missing ? also when trying to print the file it always saves it to pdf unless you choose to safe it in other type and always the downloaded file is empty meaning the pdf !

can please anyone provide for an answer i am willing to pay for the fix !!!!i need co editing !
