Files .xlsx and .docx on Cloud Onedrive open read-only

Greetings to the forum, I just bought the paid version of the Cryptomator on the Play Store to update my documentation consisting of excel and word files from both the PC and my smartphone. Unfortunately I realized that while from the Desktop version I do not have problems if I try to open a document on Cloud the document opens in “read only” mode and I can not modify my files. Can you help me ? Thank you
