Does anyone else feel like they waste their time because half the things they do even if requested get pushed aside?

I personally do a lot of automation of reports/actions for a tool I support to help my team and provide transparency for quality goals. However it feels like everytime I put time (hours-days) into actually developing a solution it gets waved away/shot down by a more senior engineer.....even if its something requested by them, usually because the tool honestly has some shit design (no api overwrite for things that can be done manually using the UI prompting workarounds) honestly makes me wonder "WTF am I here for if apparently nothing I do is good enough?" Always get great performance reviews but its really annoying and eats away at the self confidence to have my work be shut down constantly
