I know, but it seems from the author's post that they were just locked out completely with no option to use google takeout to retrieve their photos etc.
The assumption is that takeout would not work anymore once you are suspended. So unless you are proactive and takeout your data every day, you will probably lose some data
But, according to gdpr, they still have your data even if you're "suspended", so they should make it available to you.
I haven't had a suspended account yet but if google really doesn't let you copy your data under any circumstance, they will have even more fun with the data protection agencies.
