Remaining deleted successfully but after refereshing again shown in extension side. Even i have downloaded .aia file and with the help of 7zip, i deleted all those extensions with but when i uploaded it again it show server error. plz suggest and i am not able to upload it.
Do not try to delete the extension while it is connected with companion. First disconnect it and try. If not make it as aia and open the aia with 7zip and go to assets>external_comps>(delete the unwanted extension folder name) then upload this aia into project
