@pulsjet is continuing developing amaizing app Memories. Thank a lot him!
Unfortunately I got a bug in new Memories 4.12.2 and I want to return old Memories 4.11.2. How to downgrade it?
If you go on the apps page, you can find the old releases:
You can delete and put the old code in the apps-folder. However, normally downgrades are not supported and if with the last update, something in the database structure or file structure has changed, this will not work and create problems.
For that reason, check on the bug tracker, if your problem has been reported. If not you can do submit a new one. There you can also ask if it is save to go back to the previous version until the issue is fixed.
