According to the DriveHQ Plan Comparison, free accounts are supposed to have 5GB of storage space.  It has increased from 1GB to 5GB.   I've had a free account since 2017, but I only have 1GB.  Do not find any option to change it to 5 GB.  How can I take advantage of the increased storage space? Thanks! 

I have increased your max storage space to 5GB now. Please note the free service is for personal and casual use only with some feature restrictions.
