endorphin I suggest you try again to change your profile picture - it you keep failing to do so you may have found a bug which will need to be reported.
I have tried and tried on my iPad with no success. I never have accessed the preview site on any other device, and I rarely use the main site except on the iPad. I don’t really like trying to use internet on the Windows Lumia 640 (I use it as Internet radio, and to access dashboard, but not Community, and it’s not easy to use internet on it anyway, as it is Windows 8.1 mobile and no longer supported, so it is not easy to use.)
I can access Community on my laptop but I don’t generally use it except with IE to do certain actions (like upload barcodes for Shop&Scan), and only started using Edge for a few things, but don’t really like it much.
I guess it is a bug @ianmorland as I have got nowhere trying daily to upload a profile picture. I haven’t tried changing my profile picture on the main site yet, but don’t really want to mess that up! 🤡
