I've used Joplin for a few years, had a few hundred notes on it and even sponsored it on GitHub. Then I've changed my smartphone which also brought with it an updated version of Android. The new Android version had some changes regarding how an app can manage a filesystem, which ultimately broke Joplin. I've waited a few weeks for an update (couldn't read my notes on a phone then) and even when it finally arrived, the process of synchronization was so slow and buggy I couldn't do it. That (together with other sync bugs I've been reporting earlier) was the reason I've lost patience and switched to Obsidian. Either way, I'm thankful for developers for those few years, that was a really great tool
