I saw this coming ages ago when Atlassian acquired them. Trello and Jira co-existing never made any sense. I moved everything to Notion for a while, but that had its own (extremely annoying) quirks and features. I use Google Sheets now and am happy. The UI isn't flashy, but for tracking whether something's backlogged, WIP or Done, it does the job. Plus, if/when Google decides to pull the rug and RIP Sheets, I can export into an immortal copy of Excel 2010 somewhere and use it til the end of days!
