iphone Other memory hog plus free memory will not update
2 queries. first, i've read previous answers regarding Other hogging memory in iphone (se 13.4.1 in my case) but the most recent is 5 years ago and i wonder if anything has changed. one recommendation was to restore my iphone, but i talked to apple support today and they said that won't help anything. other suggestions were 3rd party software but people warn that this approach can cause trouble. Any current tips on how to reduce the memory tied up in Other?
second question, i deleted 2.8G of music out of 6.9G to free up memory but my iphone still says i have 6.9G of music and no free memory left. itunes indicates that the music files i deleted are in fact gone. i tried turning the phone off and back on twice. no change. any suggestions on getting my phone to update its memory status and give me back 2.8G of free memory?
many thanks to anyone who helps. stay safe.
