I faced similar instances last year, dating back to Jun 2020, and now am facing the same thing again. I’ll try to see a workaround like you mentioned 
Bug Data Airtable - Help - Adalo
Filtering for Airtable not working with Magic Text - Help - Adalo
I remember one workaround I found. I set up an ‘empty’ action on the Screen settings, so that every time I entered a screen that action would trigger. It didn’t always work, but it alleviated 90% of the issues. For some reason, that action would make Adalo respond to the filter properly.
For search bars, your action button would probably be the best workaround
