I am confused with the latest version of Adobe reader on iPad Pro

Hi there,

My iPad has installed the last version of Acrobat reader automatically like it should. I know it’s been several weeks since the last big update and I have been struggling with the elimina of tools Ever since.  One is the drawing of text boxes and adding text to them.  I cannot make that happen any longer.  The flattening issue has a work around as provided by one of the savvy people here...thanks.  I need that for sure.  Now, I can edit text boxes on exiting files from before the update.  But I can’t add any At all to any file....Pre update or post update.  I also cannot change the calculations of three boxes where I have a dollar amount for a job, a deposit required, which is supposed to be subtracted from the final payment due but it’s adding it????  Never did that before and now my Estimate file is useles.  Thanks for your help.
