Login issues on mobile

Hi there

I seem to be having this same issue again (linked below). Can you please check if it's the Siteground security issue again?

I can't log in on the mobile browser or the PWA. Usually if I can log in on the mobile browser, the PWA refreshes, but I can't get in on either and there's no error message that flags to give me a reason why.

Please help. Thank you 🙏
