Thank you for fixing the saving problem. But there's another problem that isn't fixed. When I want to clear cache in the telegram storage settings, it only shows the "other files" category and puts all the files there instead of putting them in different ones such as videos, music etc. This problem exists for me in 8.2+ including 8.2.2
In addition, the pictures used to be saved in Pictures/Telegram folder, but now they're saved in Pictures. I don't know if this was intentional or not, but I personally preferred the earlier way. Made it easier to organize images in gallery.
