Hello, I've been trying to use the "Combine" function in Adobe Acrobat Online to merge two PDF files but the "Combine" button continues to remain greyed out even after my two files are ready lying in the drop box. Please help.
Hello, I just solved the problem myself! All this time, I had been trying to click the "Combine" button without giving a name to the future merged file. The moment I gave a name to my merged file, the "Combine" button turned blue from grey and I could merge the two files.
