'File Not Found Error' suddenly massively appearing since yesterday

Since yesterday ERA is suddenly reporting 'File Not Found' errors on my Storage.setItem calls. Does anyone notice the same? I found some topics on this error but none with a real solution. Really wondering what's going on here, as users are getting IQ crashes on this suddenly. Mostly on Venu, Vivoactive4 & Vivoactive4s. Was there maybe some firmware update on there?
