I have purchased solid explorer app but I am very disappointed with it.
Whenever I search in my sd card or internal storage for any file (like file name having "patwar" in their name), it does not show any files. But when same thing is searched with another file explorer like "FX file explorer" it shows correctly.
Second thing, I had noticed you and emailed about the folder size not correctly shown because of .nomedia file but still no update about it. This is also correctly shown in "FX file explorer" instead of . nomedia file.
Fix these issues as soon as possible
