More issues with Legacy Gmail Suite accounts

Well, I’m running out of space, and don’t know what to do. I have a total of 115 GB of storage (the free 15 GB and the paid 100 GB I renew every year), but Google won’t let me buy more space because I’m using the Legacy Gmail Suite account. It looks like they haven’t come up with a way of allowing legacy free users to upgrade their storage.

I wonder what my alternatives are. I don’t want to delete Google Photos and accidentally delete photos from my Apple iCloud Photos, where everything is also backed up.

Anybody else run into this situation?
