We appear to have an issue adding (Upload a File) attachments to an activity. Has anyone else had any experience to ading attachments after the activity has been created.
Not sure what the limitation is. But I have tried with a max of 9 files in a task. The upload button doesn't popup after this limit. Sometimes you may also receive message "Too many files are being uploaded".
To me that limit if exists, does not make sense since files are in the end stored in SPO...but it seems something is wrong with files upload in planner tasks
