I saw yesterday that backups on all of my databases across all projects are either showing wrong size or are not working.
I backed up manually yesterday, and there seems to be correct size, but today again, it is wrong as you can see it in the screenshot.
Hope someone can check this, I doubt it is related to my account or database, since I have same problem on different projects as well.
TL;DR
Issue with automatic database backups not functioning correctly across all projects, showing wrong size or not working since the 1.8 release. Manually backed up yesterday and correct size appeared, but issue persists today. Requesting developers to investigate the problem.
