icloud photos stuck on updating
Hello everyone, I have a iphone se 1st edition model MLLN2VC/A on ios 15.8.3 and I barely have any apps installed on it but I barely have any internal storage space left. It's showing that ios takes up 6.98 GB and system data takes up 5.45 GB of data. Combined it's 12.43 GB/16 GB total. The rest is around 3.57 GB free which is available to - telegram/instagram/snapchat. I don't even have any pictures or videos. But, when I enable icloud photos and take a photo, it takes forever for it to be uploaded to icloud and icloud photos under iphone storage has a spinning wheel that says "updating" without any progress. It's as if ios keeps making more and more system data without a way to delete it and it just overwhelmes the internal storage to the point that icloud thinks there's no more internal storage and won't sync and icloud photos won't upload.
What can I do about this complicated situation ?
