microSD issues

About one month ago my hassio couldn’t start, it was some kind of issue with the file system
I managed copying most of the configuration using a linux machine, and copied to a new micro SD card

It all worked fine until one day it couldn’t write anymore
So no updates, can’t install new plugins, and if I reset it, all the new config changes are discarded

What could be the issue?
Is it possible I’ve overfilled the card or written too many times?

There is a well-known problem with fake/counterfeit versions of SanDisk SD cards coming from ebay and occasionally Amazon Marketplace vendors. Be certain you’re using a Class 10 SD card from a name brand manufacturer, preferably not SanDisk.

It was bought from a trusted vendor, but it is a SanDisk. Why are they not good and what should I buy?

I’ve had very good results with Samsung Evo Select 32GB and 64GB SD cards over the last year.
