The simple task of renaming a file located on my Windows 10 pc using my Windows 10 pc changes the modified date to the time of the rename as it displayed in Solid Explorer. Other file explorers show the proper original date modified (not the date the file was renamed). The date remains if I rename using solid explorer itself to do the rename.
I also noticed that around when this started happening, if I opened a video stored on my pc through solid exolorer (launching mx player or vlc) that even if I closed the video or played another I could not rename (and sometimes not even delete) the video until quite a few minutes went by (up to 10 minutes) when finally it would let me. I cannot find similar issues being reported. Using an original Pixel XL with Android 9, October security patch.
