This app used to work great  and was invaluable to me on many overseas trips where internet access was spotty  but the recent version is not working for me (hence the 3 stars for an otherwise 5 star product). I have a 128GB external card  and of course a smaller amount of internal storage. I go to settings and change the storage to the external SD Card (it shows I have 33GB available on that card). When I try to open a local file (clicking the SD icon and going to the local tab)  Kiwix just scans and scans and scans without finding anything. It displays """"""""Scanning for ZIM files  please wait..."""""""" and shows the wait spinner forever. Moving the ZIM files to the Kiwix folder doesn't help either. The older version was able find the ZIM files within 2-3 seconds  on the same SD Card and the same phone  using the same ROM. Please fix this. I have a month-long trip coming up to some underdeveloped areas and will be needing to read offline Wikipedia and wikivoyage ZIM files!""
